Question

-4(a+2)-1 = -5a PLEASE SHOW STEPS

Answer 1

a = 9

Explanation:

Given:

-4(a+2)-1 = -5a

Solve:

-4(a+2)-1 = -5a << Distribute {-4 × a = -4a } {-4 × 2 = -8}

-4a - 8 - 1 = -5a << Subtract {-8 - 1 = -9}

-4a - 9 = -5a << Add -4a to both side {-4a + -4a = } {-5a + -4a = -1a}

-9 = -1a << Divide both sides by -1 {-9/-1 = -1a/-1}

a = 9
