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
Answer:
8
Step-by-step 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.
