Solving the algebraic equations given, the missing numbers in the boxes can be known as shown in the steps below.

Given the equation, ⅔(x - 1) = ⅕(2x - 3) + 1

First, apply the distribution property to open the bracket.

Thus:

⅔x - ⅔ = ⅖x - ⅗ + 1

⅔x - ⅔ = ⅖x + ⅖

Subtract ⅖x from both sides

⅔x - ⅖x - ⅔ = ⅖

4/15x - ⅔ = ⅖

Add ⅔ to both sides

4/15x = ⅖ + ⅔

4/15x = 16/15

Multiply both sides by 15/4

x = 16/15 × 15/4

x = 4

Given the equation, 3c - 3 + 2(3c + 1) = - (3c + 1)

Open the bracket using distributive property

3c - 3 + 6c + 2 = -3c - 1

Add like terms

9c - 1 = -3c - 1

Add 3c to both sides

9c + 3c - 1 = -1

12c - 1 = -1

Add 1 to both sides

12c = -1 + 1

12c = 0

Divide both sides by 12

c = 0

Combine 2y+1x=40 and y=2x using substitution

fomenos

2(2x) + 1x = 40 or 4x + 1x = 40 is the result of combining by substitution

Solution:

Given that we have to combine 2y + 1x = 40 and y = 2x using substitution method

The substitution method for solving systems of equations involves expressing one variable in terms of another, thus removing one variable from an equation.

Given equations are:

2y + 1x = 40 -------- eqn 1

y = 2x ----------- eqn 2

We can substitute eqn 2 in eqn 1

Which means, substitute y = 2x in place of y in eqn 1

2(2x) + 1x = 40

4x + 1x = 40

5x = 40

x = 8

From eqn 2,

y = 2(8)

y = 16

Thus by combining using substitution method we found the solution

A board of length 7 divided by the quantity x minus 2 end of quantity meters was cut into two pieces. If one piece is 3 divided

bulgar [2K]

Answer:

Length of other board $=\frac{4x+20}{x^{2} -4}$ metres

Step-by-step explanation:

Given: Length of board = $\frac{7}{x-2}$ metres

Length of board was divided into two.

Length of one piece = $\frac{3}{x+2}$ metres

Let $l$ = length of the other board

Length of the other board = Length of board - Length of one piece

So, $l=\frac{7}{x-2}-\frac{3}{x+2}$

$l=\frac{7(x+2)-3(x-2)}{(x-2)(x+2)} \\\\l=\frac{7x+14-3x+6}{x^{2} -4} \\\\l=\frac{4x+20}{x^{2} -4}$

Thus, length of the other board $=\frac{4x+20}{x^{2} -4}$ metres

In the model below what is x and how do I solve it

tiny-mole [99]

Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.

X=6

Step-by-step explanation:

(8x-4)+(3x+17)=(17x-23)

Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.

11x+13=17x-23

Now this is what the equation should look like after combining ur alike terms.

11x+13=17x-23

-11x. -11x.

now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.

13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.

36=6x and now u just divide the 36 by 6 and remember to always divide by the x

Now the answer is x=6
