Answer:
x= 8
Step-by-step explanation:
103 - 4x = 71
You have to isolate -4x by using the subtraction property of equality on 103
103(-103) -4x = 71(-103)
-4x = -32
Use Multiplication Property of Equality for the negative
4x = 32
Divide 4 from both sides
x= 8
You just multiply 2 times 6 which is 12
so 12 cm is your answer
