Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing one or more variables.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means rearranging the equation so that the variable is on one side and all other terms are on the other side.

Front

What is the first step to solve the equation 18 + t = 50?

Back

Subtract 18 from both sides to isolate t.

Front

Solve for t: 18 + t = 50

Back

t = 32

Front

What is the first step to solve the equation 54 = s + 34?

Back

Subtract 34 from both sides to isolate s.

Front

Solve for s: 54 = s + 34

Back

s = 20

Front

What is the first step to solve the equation x + 4 = 14?

Back

Subtract 4 from both sides to isolate x.

Front

Solve for x: x + 4 = 14

Back

x = 10

Front

What is the first step to solve the equation x - 62 = 123?

Back

Add 62 to both sides to isolate x.

Front

Solve for x: x - 62 = 123

Back

x = 185
