0.5x-0.7+1.3x=6.5
Add 1.3x to both sides.
1.8x-0.7=6.5
Combine 0.5x and 1.3x to get 1.8x.
1.8x=6.5+0.7
Add 0.7 to both sides.
1.8x=7.2
Add 6.5 and 0.7 to get 7.2.
x=\frac{7.2}{1.8}
Divide both sides by 1.8.
x=\frac{72}{18}
Expand \frac{7.2}{1.8} by multiplying both numerator and the denominator by 10.
x=4
Divide 72 by 18 to get 4.
