Question

Know he answer for this???

Answer 1

8

Explanation:

Let us first sole the equation for x.

6x - 3 = 45

-> 6x = 45 + 3

-> 6x = 48

-> x = 48/6

-> x = 8

Thus 8 from the set {4, 5, 6, 7, 8} makes the equation 6x - 3 = 45 true.

Answer 2

solution = 4 ?

6 * 4 - 3 = 24 - 3 = 21 not 45 so 4 is not the solution

the solution = 8

6 * 8 - 3 = 48 - 8 = 45
