Question

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4.

1. Add 5 positive x-tiles to both sides and create zero pairs.
2. Add 4 negative unit tiles to both sides and create zero pairs.
3. Divide the unit tiles evenly among the x-tiles.

x =

Answer 2

`x=-2`

Explanation:

`-5x+(-2)=-2x+4`

`-5x+(-2)+5x=-2x+4+5x` (according to first step)

`-2= 3x+4`

`-2+(-4)=3x+4+(-4)` (according to second step)

`-6=3x`

`(-6)/(3)`=
`(3x)/(3)` (according to third step)

`-2=x`

`x=-2`

hence the solution of the given equation is
`x=-2`
