7(z +2) - 3z =44
Distribute the 7. Distributive property: a(b+c) = ab + ac
7z + 14 - 3z = 44
Simplify like terms.
4z + 14 = 44
Subtract 14 to both sides
4z = 30
Divide by 4 on both sides.
z = 7.5
Answer:
what is the question
Step-by-step explanation:
Apply distributive property
-9-9x+4=-5
Combine like terms
-5-9x=-5
Add 5 to both sides
-9x=0
Divide both sides by -9
x=0
Final answer: x=0
