Write as an equation: "A number m added to 3 equals 15"

• m + 3 = 15

• m + 15 = 3

• m - 3 = 15

Write as an equation: "A number y decrease by 4 is 3".

• y + 4 = 3

• y = 4-3

• y - 4 = 3

Write as an equation: "12 times a number p equals 48"

• 12 ÷ p = 48

• 12p = 48

• 12 + p = 48

Write as an equation: "The sum of a number n and 7 is 15"

• n - 7 = 15

• n + 7 = 15

• n = 7 + 15
