Question

Which answer choice below is a solution to this equation?7x + 5 – 2x = 2x – 7A. 2B. 0C. -4D. 8

Answer 1

Step 1:

In this question, we are given the following:

`7x\text{ + 5 - 2 x = 2 x- 7}`

Step 2:

The details of the solution are as follows:

`\begin{gathered} 7\text{ x - 5 - 2 x = 2 x - 7} \\ 5x\text{ - 5 = 2x - 7} \\ collecting\text{ like terms, we have that:} \\ 5\text{ x - 2x = - 7 - 5} \\ 3\text{ x = - 12} \\ Divide\text{ both sides by 3, we have that:} \\ x\text{ =}(-12)/(3) \\ x\text{ = - 4 \lparen OPTION C \rparen} \end{gathered}`

CONCLUSION:

The final answer is:

`x\text{ = - 4 \lparen OPTION C\rparen}`
