Answers

A) x=3 and b) x= 9/3

Answer:

x = 3

x = 4.5

Step-by-step explanation:

A) 2(5x - 3) = 24

5x - 3 = 12 (divide both sides by 2)

5x = 15 (add 3 to both sides)

x = 3 (divide both sides by 5)

B) 5(2x + 1) = 50

2x + 1 = 10 (divide both sides by 5)

2x = 9 (take 1 away from both sides)

x = 4.5 (divide each side by 2)
