Answer:
d. 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
45a−25+7a=79
45a+−25+7a=79
(45a+7a)+(−25)=79(Combine Like Terms)
52a+−25=79
52a−25=79
Step 2: Add 25 to both sides.
52a−25+25=79+25
52a=104
Step 3: Divide both sides by 52.

Answer:
2
Step-by-step explanation:
First add all your like terms.
52a - 25 = 79
Add 25 to both sides to cancel the 25 and isolate the variable.
52a = 104
Divide both sides by to find a.
a = 104/52
a = 2
