Solve 11/2-a=3/8

$$1 \frac { 1 } { 2 } - a = \frac { 3 } { 8 }$$

Solve for a

$$a = \frac{9}{8} = 1\frac{1}{8} = 1.125$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 8, the least common multiple of 2,8.

$$4\left(1\times 2+1\right)-8a=3$$

Multiply 1 and 2 to get 2.

$$4\left(2+1\right)-8a=3$$

Add 2 and 1 to get 3.

$$4\times 3-8a=3$$

Multiply 4 and 3 to get 12.

$$12-8a=3$$

Subtract 12 from both sides.

$$-8a=3-12$$

Subtract 12 from 3 to get -9.

$$-8a=-9$$

Divide both sides by -8.

$$a=\frac{-9}{-8}$$

Fraction \frac{-9}{-8} can be simplified to \frac{9}{8} by removing the negative sign from both the numerator and the denominator.

$$a=\frac{9}{8}$$
