Let's call the number x. So four times the number minus five would look like
4x-5
Twice the number plus three would look like
2x+3
Now make the two equations equal
4x-5=2x+3
I'm going to subtract 2x from each side
2x-5=3
Now I'm going to add five to each side
2x=8
Now divide both sides by 2
x=4
To double check, just plug back into the original equations
4(4)-5=11
2(4)+3=11
They are equal, so the answer is x=4.

Step-by-step explanation:

Let the number be x,

Then, according to the question,

4x-5=2x+3

(we need to find the value of x)

4x-2x=5+3

= 2x=8

= x=8/2

= x=4

HELP!!! ASAP!
Feliz [49]

The solution to given system of equations is (x, y) = (\frac{-15}{263} , \frac{-115}{263})

The given equation has one solution

<em><u>Solution:</u></em>

Given system of equations are:

12x - 13y = 5 --------- eqn 1

x = 23y + 10 --------- eqn 2

We have to solve the system of equations by substitution

<em><u>Substitute eqn 2 in eqn 1</u></em>

12(23y + 10) - 13y = 5

276y + 120 - 13y = 5

263y = 5 - 120

263y = -115

y = \frac{-115}{263}

<em><u>Substitute the above value of "y" in eqn 2</u></em>

x = 23 \times \frac{-115}{263} + 10\\\\x = \frac{-2645}{263} + 10\\\\x = \frac{-2645 + 2630}{263}\\\\x = \frac{-15}{263}

Thus the solution to given system of equations is (x, y) = (\frac{-15}{263} , \frac{-115}{263})

Thus the given equation has one solution

jasenka [17]

Answer:

1 = The Value of the expression is 10 for x = 3 and y = 2

2 = The Value of the expression is 10 for x = 3 and y = 2

3 = The Value of the expression is 10 for x = 2 and y = 3

4 = The Value of the expression is 10 for x = 2 and y = 3

5 = The Value of the expression is 10 for x = 2 and y = 3

6 = The Value of the expression is 10 for x = 3 and y = 2
