Answer:
Step-by-step explanation:
multiply the 9
81 - 72x = 2x + 3
get the x's on one side and constants on the other
78 = 74x
divide by 74
78/74 = x = 39/37
I'm not sure though pls mark brainiest
81-72x = 2x + 3
-74x = -84
x = 84/74= 42/37
-81 + 72x = 2x + 3
70x = 84
x = 84/70= 42/35= 6/5
-74x = -84
x = 84/74= 42/37
-81 + 72x = 2x + 3
70x = 84
x = 84/70= 42/35= 6/5
