0.4x+2-0.3x=17
Use the distributive property to multiply 0.4 by x+5.
0.1x+2=17
Combine 0.4x and -0.3x to get 0.1x.
0.1x=17-2
Subtract 2 from both sides.
0.1x=15
Subtract 2 from 17 to get 15.
x=\frac{15}{0.1}
Divide both sides by 0.1.
x=150
Expand \frac{15}{0.1} by multiplying both numerator and the denominator by 10. Anything divided by one gives itself.
