0.8x+0.8-1.29x=3.74
Subtract 1.29x from both sides.
-0.49x+0.8=3.74
Combine 0.8x and -1.29x to get -0.49x.
-0.49x=3.74-0.8
Subtract 0.8 from both sides.
-0.49x=2.94
Subtract 0.8 from 3.74 to get 2.94.
x=\frac{2.94}{-0.49}
Divide both sides by -0.49.
x=\frac{294}{-49}
Expand \frac{2.94}{-0.49} by multiplying both numerator and the denominator by 100.
x=-6
Divide 294 by -49 to get -6.
