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.
