Answer:
-2
Step-by-step explanation:
-3(-2) - 1 is equal to 5. And 2(-2) is equal to -4.
The question says:
4(x) +3 = 2(x) + 9
so now you need to find x
first you should add -2(x) on both sides of the equation and then add -3 on both sides:
4(x) - 2(x) = 9 - 3
2(x) = 6
now you can divide both sides by 2:
x = 6/2
x = 3 :)))
I hope this is helpful
