Solve: 5 (x + 2) = 3x + 5

A. X=-5/2

B. X=-13/15

C. X=10/11

D. X=5

A. X = - 5/2

There are multiple ways to solve this problem.

One way is by substituting each of the given value options as X into the equation. If both sides are equal, then that's the answer.

But if there were no options and not a lot of time left to answer the problem this way, then you would solve for x regularly.

Start out distributing the 5 into the parentheses. So you would multiply 5 by x and by 2. You would the. Have an equation like this:

5x+10 = 3x+5.

After that you want to either subtract 5 or 10 on both sides.

I subtracted 5.

Then you would want the variables on one side so you would subtract 5x on both sides. This will leave you to an equation of:

5 = - 2x.

Finally you would want to divide - 2 on both sides.
