1.5x-20=0.7x+4
Use the distributive property to multiply 5 by 0.3x-4.
1.5x-20-0.7x=4
Subtract 0.7x from both sides.
0.8x-20=4
Combine 1.5x and -0.7x to get 0.8x.
0.8x=4+20
Add 20 to both sides.
0.8x=24
Add 4 and 20 to get 24.
x=\frac{24}{0.8}
Divide both sides by 0.8.
x=\frac{240}{8}
Expand \frac{24}{0.8} by multiplying both numerator and the denominator by 10.
x=30
Divide 240 by 8 to get 30.
