Answer:
z = 10
Step-by-step explanation:
Distribute 2 to the terms in the parentheses:
2(2z + 5) = 50
4z + 10 = 50
Subtract 10 from both sides
4z = 40
Divide each side by 4
So, the answer is z = 10
10
1. Factorize left side.
2*2z+2*5=50
4z+10=50
2. Subtract 10 from both sides
4z=50-10
4z=40
3. Divide both sides by 4
z=40/4
z=10
6x
add sides up
