Question

If 8x-4=6x-10, find the value of 3x

Answer 1

`3x = -9`

Explanation:

Move all terms containing x to the left side of the equation.

`2x-4=-10`

Move all terms not containing x to the right side of the equation.

`2x=-6`

Divide each term by
`2` and simplify.

`x=-3`

Replace the variable
`x` with
`-3` in the expression.

`3(-3)`

Multiply
`3` by
`-3`

`-9`

Answer 2

8x - 4 = 6x - 10
8x - 6x = - 10 + 4
2x = -6
x = -3
3x = -9
