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.

52a

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
