Answer:
Left to right: Zoe, Johana, Kami, Craig
Explanation:
The values of x can be found by solving each of the equations.
A) x/-12 -2 = -22 ⇒ x = -12(-22 +2) = 240 . . . (first step: add 2)
B) 3x -21 = 15 ⇒ x = (15 +21)/3 = 12
C) -12x +2 = -22 ⇒ x = (-22 -2)/-12 = 2 . . . (first step: subtract 2)
D) 1/2x +66 = 126 ⇒ x = 2(126 -66) = 120
__
Zoe's equation requires adding 2 as the first step. It is equation A.
Craig's equation's solution is half that of Zoe's. 240/2 = 120. Craig's is equation D.
Kami's equation requires subtracting 2 as the first step. It is equation C.
Johana's equation's solution is 6 times that of Kami's. 6·2 = 12. Johana's is equation B.
