Sawyer Villegas · Answer 1

4a-9b=22

substitute b=-2

4a - 9 (-2) = 22

4a + 18 = 22

subtract 18 from each side

4a = 4

divide by 4

a = 1

Choice C

Chloe · Answer 2

a=1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4a+18=22

Step 2: Subtract 18 from both sides.

4a+18-18=22-18

4a=4

Step 3: Divide both sides by 4.

4a / 4 = 4 / 4

a=1
