Solve 1=a(25/4)+3

$$1 = a ( \frac { 25 } { 4 } ) + 3$$

Solve for a

$$a=-\frac{8}{25}=-0.32$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$a\times \frac{25}{4}+3=1$$

Subtract 3 from both sides.

$$a\times \frac{25}{4}=1-3$$

Subtract 3 from 1 to get -2.

$$a\times \frac{25}{4}=-2$$

Multiply both sides by \frac{4}{25}, the reciprocal of \frac{25}{4}.

$$a=-2\times \frac{4}{25}$$

Express -2\times \frac{4}{25} as a single fraction.

$$a=\frac{-2\times 4}{25}$$

Multiply -2 and 4 to get -8.

$$a=\frac{-8}{25}$$

Fraction \frac{-8}{25} can be rewritten as -\frac{8}{25} by extracting the negative sign.

$$a=-\frac{8}{25}$$
