Question

Four times a number decreased by 25

is the same as the opposite of the number. Find the number

Answer 1

x = 5

Explanation:

Translate the word problem into an equation and solve for x

4x - 25 = -x

Add 25 to both sides

4x = -x + 25

Add x to both sides

5x = 25

Divide both sides by 5

x = 5
