Answer:
-27
Step-by-step explanation:
-2/3 a-6=12
Collect like terms
-2/3 a=12+6
-2/3 a=18
Divide both sides by -2/3
-2/3 a/ -2/3= 18/ -2/3
a=18/ -2/3
a=18X-3/2
9 X -3
a=-27
To check whether we are correct, we substitute a with -27 in the equation given
-2⁄3 a − 6 = 12
-2⁄3 (-27) − 6 = 12
-2(-9)-6=12
18-6=12
12=12
