Question

Solve for variable and explain each step: 6x-3=15​

Answer 1

x=3

Explanation:

6x-3=15

First, you put the x on the left side and all the numbers on the right side.

6x=15+3

When you move a symbol to the other side of the equation, the sign in front of it will change to the other side.

So, we have: 6x=15+3 or 6x=18.

Since 6x=18, then x=18/6 or 3.

Answer 2

x= 3

Explanation:

6x-3=15​

we sum by 3 both sides of the equation:

6x-3 +3=15​+3

we have:

6x = 18

we divide by 6 both sides of the equation:

6x/6=18/6

we have:

x= 3
