Solve the following: a) 2(5x – 3) = 24 b) 5(2x + 1) = 50

likoan [24]

Answer:

x = 3 and x = $\frac{9}{2}$

Step-by-step explanation:

(a)

2(5x - 3) = 24 ( divide both sides by 2 )

5x - 3 = 12 ( add 3 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

(b)

5(2x + 1) = 50 ( divide both sides by 5 )

2x + 1 = 10 ( subtract 1 from both sides )

2x = 9 ( divide both sides by 2 )

x = $\frac{9}{2}$
