0.06x+0.09x-1.35=0.07\times 15
Use the distributive property to multiply 0.09 by x-15.
0.15x-1.35=0.07\times 15
Combine 0.06x and 0.09x to get 0.15x.
0.15x-1.35=1.05
Multiply 0.07 and 15 to get 1.05.
0.15x=1.05+1.35
Add 1.35 to both sides.
0.15x=2.4
Add 1.05 and 1.35 to get 2.4.
x=\frac{2.4}{0.15}
Divide both sides by 0.15.
x=\frac{240}{15}
Expand \frac{2.4}{0.15} by multiplying both numerator and the denominator by 100.
x=16
Divide 240 by 15 to get 16.
