Choose all that correctly solve for x.

A. 5/2 x = 15/2
x = 3
B. x + 7/2 = 7
x = 7/2
C. x + 3 = 21/5
x = 5/6
D. 5x = 11/2
x = 10/11.

Answer:

Options: A, B, and C correctly solve for x.

Explanation:

A).


(5)/(2) x =
(15)/(2)

Multiplying both sides by 2 gives;

5x = 15

x = 15 ÷ 5 = 3

∴ This option correctly solve for x.

B).

x +
(7)/(2) = 7

x = 7 -
(7)/(2) =
(14)/(2) -(7)/(2) = (7)/(2)

∴ This option correctly solve for x.

C).

x + 3 =
(21)/(5)

x =
(21)/(5) - (15)/(5) = (6)/(5)

But the option give x as 5/6 hence this option does not correctly solve for x.

D).

5x = 11/2

x = 11/2 ÷ 5 = 11/2 × 1/5 = 11/10

But the option gives x as 10/11 so it does not correctly solve for x.
