In this worksheet, find the missing numbers in the equation.
In algebra, we use a letter to represent the unknown number.
|1 + x = 4. x =||
To solve, use the inverse of addition, which is subtraction, to isolate the variable x.
x = 4 - 1
x = 3
|4y = 24. y =||
To solve, use the inverse of multiplication, which is division, to isolate the variable y.
y = 24 ÷ 4
y = 6
