0.8x-0.32=0.4x+7
Use the distributive property to multiply 0.16 by 5x-2.
0.8x-0.32-0.4x=7
Subtract 0.4x from both sides.
0.4x-0.32=7
Combine 0.8x and -0.4x to get 0.4x.
0.4x=7+0.32
Add 0.32 to both sides.
0.4x=7.32
Add 7 and 0.32 to get 7.32.
x=\frac{7.32}{0.4}
Divide both sides by 0.4.
x=\frac{732}{40}
Expand \frac{7.32}{0.4} by multiplying both numerator and the denominator by 100.
x=\frac{183}{10}
Reduce the fraction \frac{732}{40} to lowest terms by extracting and canceling out 4.
