(worth 10 points) 2x + 5 = 7x - 15

Karolina [17]

Answer:

The solution for the equation is $x = 4$ .

Step-by-step explanation:

-Solve the equation:

$2x +5=7x -15$

-Subtract 7x from 2x:

$2x +5 -7x=7x -7x -15$

$-5x + 5=-15$

-Subtract both sides by 5:

$2x + 5 - 5 = -15 -5$

$-5x = -20$

-Divide both sides by -5:

$\frac{-5x}{-5} = \frac{-20}{-5}$

$x = 4$

So, the answer is $x = 4$ .
