Question

Which equations have the same value of x as 3/5(30x - 15) = 72? Select three options.
18x - 15 = 72
50x - 25 = 72
18x - 9 = 72
3(6x - 3) = 72
x = 4.5

Answer 1

Answer:

leaving 50x-25=7 all has the same value of x

Step-by-step explanation:

50x-25=72

50x=72+25

x=97÷50

x=1.94

which is not matching to 4.5

Answer 2

Answer:

Step-by-step explanation:

(3/5)(30x - 15) = 72 ⇔ 18x - 9 = 72

(3/5)(30x - 15) = 72 ⇔ 3(6x - 3) = 72

(3/5)(30x - 15) = 72 ⇒ x = 4.5
