Solve a4/7+2=0

$$a \frac { 4 } { 7 } + 2 = 0$$

Solve for a

$$a = -\frac{7}{2} = -3\frac{1}{2} = -3.5$$

Steps for Solving Linear Equation

Subtract 2 from both sides. Anything subtracted from zero gives its negation.

$$a\times \frac{4}{7}=-2$$

Multiply both sides by \frac{7}{4}, the reciprocal of \frac{4}{7}.

$$a=-2\times \frac{7}{4}$$

Express -2\times \frac{7}{4} as a single fraction.

$$a=\frac{-2\times 7}{4}$$

Multiply -2 and 7 to get -14.

$$a=\frac{-14}{4}$$

Reduce the fraction \frac{-14}{4} to lowest terms by extracting and canceling out 2.

$$a=-\frac{7}{2}$$
