0.7x-7-0.3x=-5
Subtract 0.3x from both sides.
0.4x-7=-5
Combine 0.7x and -0.3x to get 0.4x.
0.4x=-5+7
Add 7 to both sides.
0.4x=2
Add -5 and 7 to get 2.
x=\frac{2}{0.4}
Divide both sides by 0.4.
x=\frac{20}{4}
Expand \frac{2}{0.4} by multiplying both numerator and the denominator by 10.
x=5
Divide 20 by 4 to get 5.
