1.5x-2.8-0.8x=1.4
Subtract 0.8x from both sides.
0.7x-2.8=1.4
Combine 1.5x and -0.8x to get 0.7x.
0.7x=1.4+2.8
Add 2.8 to both sides.
0.7x=4.2
Add 1.4 and 2.8 to get 4.2.
x=\frac{4.2}{0.7}
Divide both sides by 0.7.
x=\frac{42}{7}
Expand \frac{4.2}{0.7} by multiplying both numerator and the denominator by 10.
x=6
Divide 42 by 7 to get 6.
