4.3x=4x+12
Use the distributive property to multiply 4 by x+3.
4.3x-4x=12
Subtract 4x from both sides.
0.3x=12
Combine 4.3x and -4x to get 0.3x.
x=\frac{12}{0.3}
Divide both sides by 0.3.
x=\frac{120}{3}
Expand \frac{12}{0.3} by multiplying both numerator and the denominator by 10.
x=40
Divide 120 by 3 to get 40.
