Answer:

x = 4

Step-by-step explanation:

3x -5 = -2 + 9

-2 + 9 = 7 so now its 3x - 5 = 7

add 5 to the -5 so it cancels itself out. then add the 5 to 7 so it become 12. the you have 3x = 12

divide 12 ÷ 3 = 4

x = 4

The answer is x = 4.
3x - 5 = -2 + 9
add -2 + 9 and that gives you 7 so now
3x - 5 = 7 you add -5 on both sides but when you switch the -5 over with the 7 is becomes +5 so now you have 3x = 12 since 5 + 7 is 12
then you’ll divide 3 on both sides and that leaves you with x = 4
