Answer:
a=9
Step-by-step explanation:
2/3 (a-18)=-6
a−18=−6×( 3/2)
a−18=−6×3/2
a−18= −18/2
a−18=−9
a=−9+18
A=9
Simplify both sides of the equation.
2/3(a−18)=−6
(2/3)(a)+(2/3)(−18)=−6(Distribute)
2/3a+-12=-6
2/3a-12=-6
Add 12 to both sides.
2/3a−12+12=−6+12
2/3a=6
Multiply both sides by 3/2
(3/2)* (2/3a)= (3/2)* (6)
