Question

How do you solve 5x+7=3x-5

Answer 1

Subtract 3x from both sides then isolate the variable.
Sooooo...
5x+7=3x-5
2x+7=-5
2x=-12
x=-6

Answer 2

5x + 7 = 3x - 5

First, subtract 3x from both sides.

`5x = 7 - 3x = -5`
Second, keep the 7 and subtract the 5x - 3x to get 2x.

`2x + 7 = -5`
Third, subtract the 7 from both sides.

`2x = -5 - 7`
Fourth, simplify -5 - 7.

`2x = -12`
Fifth, take the 2 and divide it on both sides, leaving just x in its place.

`x = -(12)/(2)`
Sixth, since 6 goes into 2 to get 12, simplify the fraction to 6.

`x = -6`

Answer: x = -6
