responses.
Student
Byron
Emmy
Kora
Salvador
Response
x = 12
x = 16
x = -12
x = -9
Which student finds the solution correctly?
O Byron
O Emmy
O Kora

Answer 1

Byron, x = 12

Explanation:

Because for x = 12 LHS and RHS of the given equation produces equal values.

LHS = 3/4 x +7 = 3/4*12 + 7 = 9 + 7 = 16

RHS = x + 4 = 12 + 4 = 16

LHS = RHS
