Answer:
x=3
Explanation:
Step 1: Simplify both sides of the equation.
5x−(8−4x)=2x+13
5x+−1(8−4x)=2x+13(Distribute the Negative Sign)
5x+(−1)(8)+−1(−4x)=2x+13
5x+−8+4x=2x+13
(5x+4x)+(−8)=2x+13(Combine Like Terms)
9x+−8=2x+13
9x−8=2x+13
Step 2: Subtract 2x from both sides.
9x−8−2x=2x+13−2x
7x−8=13
Step 3: Add 8 to both sides.
7x−8+8=13+8
7x=21
Step 4: Divide both sides by 7.
7x
7
