4x+2.1=6.5
Multiply 3 and 0.7 to get 2.1.
4x=6.5-2.1
Subtract 2.1 from both sides.
4x=4.4
Subtract 2.1 from 6.5 to get 4.4.
x=\frac{4.4}{4}
Divide both sides by 4.
x=\frac{44}{40}
Expand \frac{4.4}{4} by multiplying both numerator and the denominator by 10.
x=\frac{11}{10}
Reduce the fraction \frac{44}{40} to lowest terms by extracting and canceling out 4.
