-3.8x+2.5+3.4x=1.3
Add 3.4x to both sides.
-0.4x+2.5=1.3
Combine -3.8x and 3.4x to get -0.4x.
-0.4x=1.3-2.5
Subtract 2.5 from both sides.
-0.4x=-1.2
Subtract 2.5 from 1.3 to get -1.2.
x=\frac{-1.2}{-0.4}
Divide both sides by -0.4.
x=\frac{-12}{-4}
Expand \frac{-1.2}{-0.4} by multiplying both numerator and the denominator by 10.
x=3
Divide -12 by -4 to get 3.
