Question

What are the solutions of 3x+5=2x-7

Answer 1

`3x+5=2x-7` equation


`x+5=-7` Subtract 2x from both sides


`x=-12` Subtract 5 from both sides




`3(-12)+5=2(-12)-7` Plug in for X


`-36+5=-24-7` Distribute 3 and 2 into -12


`-31=-31` simplified by + and -

Answer 2

So you need to isolate the variable in order to get your answer. This is how you do it.

3x + 5 = 2x - 7
Subtract 2x from both sides.
1x + 5 = -7
Subtract 5 from both sides to have the variable by itself.
1x = -12
Divide 1 to both sides to find the value of x.
x = -12

Now we need to check.
3(-12) + 5 = 2(-12) - 7
-36 + 5 = -24 - 7
-31 = -31
Since both sides or the same you now know that -12 is the solution.
