-2.9x=x+3
Combine 4x and -6.9x to get -2.9x.
-2.9x-x=3
Subtract x from both sides.
-3.9x=3
Combine -2.9x and -x to get -3.9x.
x=\frac{3}{-3.9}
Divide both sides by -3.9.
x=\frac{30}{-39}
Expand \frac{3}{-3.9} by multiplying both numerator and the denominator by 10.
x=-\frac{10}{13}
Reduce the fraction \frac{30}{-39} to lowest terms by extracting and canceling out 3.
