Solve 2x+a=55%

$$2 x + a = 55 \%$$

Solve for a

$$a=\frac{11}{20}-2x$$

Solution Steps

Reduce the fraction \frac{55}{100} to lowest terms by extracting and canceling out 5.

$$2x+a=\frac{11}{20}$$

Subtract 2x from both sides.

$$a=\frac{11}{20}-2x$$

Solve for x

$$x=-\frac{a}{2}+\frac{11}{40}$$

Steps for Solving Linear Equation

Reduce the fraction \frac{55}{100} to lowest terms by extracting and canceling out 5.

$$2x+a=\frac{11}{20}$$

Subtract a from both sides.

$$2x=\frac{11}{20}-a$$

Divide both sides by 2.

$$\frac{2x}{2}=\frac{\frac{11}{20}-a}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$x=\frac{\frac{11}{20}-a}{2}$$

Divide \frac{11}{20}-a by 2.

$$x=-\frac{a}{2}+\frac{11}{40}$$
