Question

Which value of x is a solution of the inequality?

​ 4x+7≥35 ​


x = 6

x = 7

x = 3

x = 0

Answer 1

x = 7

Explanation:

Just try all the choices and see which one gives a valid answer

​ 4x+7≥35 ​

x = 6 : 4 (6) + 7 = 31 is NOT ≥35 (not valid)

x = 7 : 4 (7) + 7 = 35 IS ≥35 (valid) (ANSWER)

x = 3 : 4 (3) + 7 = 19 is NOT ≥35 (not valid)

x = 0 : 4 (0) + 7 = 7 is NOT ≥35 (not valid)

Answer 2

x = 7

Explanation:

Just try all the choices and see which one gives a valid answer

​ 4x+7≥35 ​

x = 6 : 4 (6) + 7 = 31 is NOT ≥35 (not valid)

x = 7 : 4 (7) + 7 = 35 IS ≥35 (valid) (ANSWER)

x = 3 : 4 (3) + 7 = 19 is NOT ≥35 (not valid)

x = 0 : 4 (0) + 7 = 7 is NOT ≥35 (not valid)
