Question

Which of the following shows the correct solution steps and solution to 2×+ 7 = -11?

Answer 1

The answer is:

x = -9

Work/explanation:

The point of equations is to find the variable's value by isolating it step-by-step.

For this equation, the variable is x.

To isolate it, I will perform a few operations.

First, I will subtract 7 from each side:

`\sf{2x+7=-11}`

`\sf{2x=-11-7}`

`\sf{2x=-18}`

Divide each side by 2

`\sf{x=-9}`

Hence, x = -9.

`\rule{350}{4}`

Answer 2

x = - 9

Explanation:

2x + 7 = - 11 ( subtract 7 from both sides )

2x = - 18 ( divide both sides by 2 )

x = - 9
