First you isolate x by subtracting 2.5 from both sides of the equation:
x+ 2.5 -2.5 = -1.4 -2.5
Do the math. The positive and negative 2.5's cancel out and you are left with the answer:
x = -3.9

Subtract 2.5 from both sides, because you need to get x by itself. Anything you do on one side, you have to do to the other, so -1.4-2.5 is -3.9.

Easy- You just subtract 2.5 from -1.4. The answer is x=-3.9.

isn't it -3.9? I think so because you would move the 2.5 over to the other side, making it become negative. and Just add the -1.4 together with the -2.5

x + 2.5 = -1.4
-2.5 -2.5 (subtract 2.5 on each side of the = sign)
x = -3.9

x+2.5=-1.4 subtract 2.5 from both sides
x= -3.9

You have to isolate the x
so, subtract the 2.5 from both sides
x= -3.9

x + 2.5 = - 1.4 (subtract both sides by -2.5)
x + 0 = -1.4 - 2.5
x= - 3.9

All that you have to do is get x by itself. you do this by subtracting 2.5 from each side because it's on the side of x.
You should end up with
x=-3.9

x is -3.9
if you add 2.5 to -3.9 you get -1.4
