38

1) Starting from the first equation

3x +6 = 18 Subtract 6 from both sides

3x = 18 -6

3x = 12 Divide both sides by 3

x =4

2) Since x =4, let's plug that into the second expression 10x -2 to find out "what is 10x -2"

10x -2 Replace x, by 4

10(4) -2 Effectuate the multiplication

40 -2

38

Hence, the answer is 38
