    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

    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
