How to Solve One-Step Equations


1) Solve for x.

x - 23 = 8

Answer

Add both sides of the equation by 23.

x=31

2) Solve for n.

n + 2 = 9

Answer

Subtract both sides of the equation by 2.

n=7

3) Solve for k.

9k = - 27

Answer

Divide both sides by 9.

k=-3

4) Solve for a.

{\Large{a \over 2}} = 6

Answer

Multiply both sides by 2.

a=12

5) Solve for y.

y + {\large{1 \over 4}} = {\large{1 \over 2}}

Answer

Subtract both sides by \large{1 \over 4}.

y=1/2

6) Solve for m.

0.25\,m = 2

Answer

Divide both sides of the equation by 0.25.

m=8

7) Solve for d.

{\Large{2 \over 3}}d = 10

Answer

Multiply both sides of the equation by the reciprocal of the coefficient. The coefficient is \large{{2 \over 3}}, therefore the reciprocal is \large{{3 \over 2}}.

d=15

8) Solve for r.

{\Large{r \over {0.5}}} = 30

Answer

Multiply both sides by the decimal number 0.5.

r=15
