Answer:
13.7
Step-by-step explanation:
3x=41
x is around 13.7
x = [tex]\frac{41}{3}[/tex]
x ≈ 13.7
[tex]3x+15=56\\3x+15-15=56-15\leftarrow \text {Subtraction Property of Equality} \\3x=41\\\\\frac{3x}{3} =\frac{41}{3} \leftarrow \text {Division Property of Equality}\\\\\boxed {x=\frac{41}{3}}[/tex]
41/3 = 13.66666666....
13.666... ≈ 13.7
