Question

Given the equation y = 3x − 4, what is the value of x when y = 5? A) 3 B) 6 C) 9 D) 12

Answer 1

A. 3

Explanation:

The answer would be A because 3 times 3 is 9 and 9-4=5 which is the value o f y. 3x-4=5

add 4 to both sides: 3x=5+4

simplify: 5+4=9

divide both sides by 3: x= 9/3

simplify 9/3 to 3:

x= 3

hope this helps!!
