3x - 2(2x - 5) = 2(x + 3) - 8

nataly862011 [7]

Answer:

x = 4

Step-by-step explanation:

Hello!

We can solve for x by expanding the parentheses and isolating x.

<h3>Solve for x</h3>

3x - 2(2x - 5) = 2(x + 3)-8
3x - 4x + 10 = 2x + 6 - 8
-x + 10 = 2x - 2
10 = 3x - 2
12 = 3x
x = 4

The value of x is 4.
