0x+0.75=2.5x+4
Multiply 0 and 25 to get 0.
0+0.75=2.5x+4
Anything times zero gives zero.
0.75=2.5x+4
Add 0 and 0.75 to get 0.75.
2.5x+4=0.75
Swap sides so that all variable terms are on the left hand side.
2.5x=0.75-4
Subtract 4 from both sides.
2.5x=-3.25
Subtract 4 from 0.75 to get -3.25.
x=\frac{-3.25}{2.5}
Divide both sides by 2.5.
x=\frac{-325}{250}
Expand \frac{-3.25}{2.5} by multiplying both numerator and the denominator by 100.
x=-\frac{13}{10}
Reduce the fraction \frac{-325}{250} to lowest terms by extracting and canceling out 25.
