Answer:
no
Step-by-step explanation:
5x - 3 = 12
5x=12+3
x=15/5=3
x=3
substitute x with 7 to find if it is a solution :
5(7)-3=12
35-3 ≠12 ( so no 7 is not a solution)
1 cm was multiplied by ten, so wee need to do that on the other side too.
1 times 10 = 10 cm, so 4 times 10 = 40 meters,
So your answer is 40 meters. Hope it helps!

to both sides.

To isolate x, divide both sides by 7.
