3.5x+1.8=12.3
Multiply 0.3 and 6 to get 1.8.
3.5x=12.3-1.8
Subtract 1.8 from both sides.
3.5x=10.5
Subtract 1.8 from 12.3 to get 10.5.
x=\frac{10.5}{3.5}
Divide both sides by 3.5.
x=\frac{105}{35}
Expand \frac{10.5}{3.5} by multiplying both numerator and the denominator by 10.
x=3
Divide 105 by 35 to get 3.
