Question

What is 3x/2+7=13 i don't know how to salve this problun

Answer 1

your answer is 39.

First you would add 7 and 2 to get 9. From there you would get the equation 3x/9=13.

Then you would multiple by the reciprocal, or 9/1 to cancel out 3x/9.

Then u multiply 9×13 because what u do to one side you have to do to the other.

Your equation should now say 3x=117.

Finally divide by 3 to solve for x.

X=39.
