Question

Form an equation of the form ax + b = c, where a, b and c are constants, such that the
solution of the equation is x = 4.
(A) 2x + 5 = 15 (B) 7x + 2 = 10 (C) 5x + 4 = 16
(D) 3x + 4 = 16​

Answer 1

Answer:

D

Step-by-step explanation:

3x= 16-4

3x=12

x=12/3

x=4

Answer 2

Answer:

3x+4=16

3x=12

dividing both sides by 3,

3x/3=12/3

X=4
