1.regroup terms: 3-x=-3x+23
2. subtract 3 from both sides: -x=-3x+23-3
3. simplify -3x+23-3 to -3x+20: -x=-3+20
4. add 3x to both sides: -x+3x=20
5. simplify 3x=20 to 2x: 2x=20
6. divide both sides by 2: x=20/2
7. simplify: x=10
ANSWER: x=10

Answer:

x=10

Step-by-step explanation:

-x+ 3 = - 3x + 23\\2x+3=23 \\2x=20\\x=10

1. Subtract -3x from both sides of equation

2. Subtract 3 from both sides of equation

3. Divide both sides by 2

\text{Let the side of square 1, square 2 and square 3 be x, y and z respectively.}\\\\\text{Given that,}\\\\\text{Perimeter of square 1,~~ p  =100 units.}\\\\\text{So}~ x=\dfrac p 4 =  \dfrac{100}4 =25~\text{units.}\\\\\\\text{Area of square 2, a = 225 units}^2\\\\\text{So}~y = \sqrt{a} = \sqrt {225} = 15~ \text{units.}\\\\\text{Use Pythagorean theorem to find z}^2\\\\x^2 =y^2 +z^2 \\\\\implies 25^2 = 15^2 +z^2\\\\\implies z^2 = 625 - 225 = 400\\\\\\

\text{Hence the area of square 3 is 400 units}^2.

What is the solution to the following system of equations 4x + 2 = -2y 6y - 18 = 6x
Pavel [41]

Answer:

The solution to the system of equations are;

x = -4/3

y = 5/3

Step-by-step explanation:

To find the Solution, we would carry the Operation simultaneously.

4x + 2 = -2y .........(i)

6y - 18 = 6x ..........(ii)

First let's rearrange the equations, to make the journey smoother

2y + 4x = -2 ...........(iii)

6y - 6x = 18 ...........(iv)

Let's Multiply equation (III) by 3 so as to have a uniform spot to begin elimination.

3.2y + 3.4x = -2 . 3

6y + 12x = -6............... (v)

Let's subtract equation (v) from equation (iv)

= 0y - 18x = 24

-18x = 24

x = - 24 / 18

x = -4/3

Let's substitute (x = -4/3) in equation (ii), so that we can solve for the value of y:

6y - 18 = 6x

6y - 18 = 6 (-4/3)

6y - 18 = -8

6y = -8 + 18

6y = 10.

y = 10 / 6

y = 5/3

The solution to the system of equations are;

x = -4/3

y = 5/3
