Question

If 10x+11=-19, what is the value of x?

Answer 1

x = -3

Explanation:

`10x + 11 = -19`

`10x = -11 -19 = -30`

`x = -30/10 = -3`

Answer 2

`x=-3`

Explanation:

`10x+11=-19`

`10x=-19-11`

`10x=-30`

`x=-3`

Answer 3

`x=-3`

Explanation:

`10x = -19-11`

`10x=-30`

`(10x)/10=-30/10`

`x=-3`

Answer 4

`x=-3`

Explanation:

Solve:

`10x+11=-19`

We want to get `x` on one side.

Subtract `11` from both sides.

`10x+11-11=-19-11`

Simplify.

`10x+0=-30`

`10x=-30`

Divide both sides by `10`. Cancel `10` on the left-hand side.

`color(red)cancel(color(black)(10))^1/color(red)cancel(color(black)(10))^1x=-30/10`

Simplify.

`x=-3`
