Answer:

x=-4

Step-by-step explanation:

Start by subtracting 5 on both side of the equation and you will be left with

  • 3x=-12

Now, divide 3 on both side of the equation and you will get x=-4
3x+5=-7
First you subtract 5 from both sides which will cancel out the +5 and -5 then subtract -7 and -5 which will give you -12
3x=-12
Divide 3 to both sides to get x by itself and divide -12 by 3 which will give you -4
Answer -4
