0.05x=0.09x+1.8
Use the distributive property to multiply 0.09 by x+20.
0.05x-0.09x=1.8
Subtract 0.09x from both sides.
-0.04x=1.8
Combine 0.05x and -0.09x to get -0.04x.
x=\frac{1.8}{-0.04}
Divide both sides by -0.04.
x=\frac{180}{-4}
Expand \frac{1.8}{-0.04} by multiplying both numerator and the denominator by 100.
x=-45
Divide 180 by -4 to get -45.
