Question

Solve: 7.1+x=30

x= 37.1


x= 22.9


x= 23.1


x= 23.9

Answer 1

Your answer would be x=22.9 when you subtract 7.1 on both sides

Answer 2

When solving for a variable, the first step is almost always to isolate the variable. This means to cancel out any other terms on its side of the equation, or move it to the opposite side. Here, we can just cancel the terms.

7.1 + x = 30
7.1 - 7.1 + x = 30 - 7.1
x = 22.9

Nothing further needs to be done with this topic as we already have the value of a singular x expressed as a simplified number.
