Answer:

4) 5

Step-by-step explanation:

3x-x+2=12

First, you combine similar terms, so 3x-x which is 2x.

Second, you subtract 2 on both sides which is going to give you 2x=10.

Finally, you divide by 2 on both sides, so the final answer is going to be x=5.

How do you solve this
kobusy [5.1K]

Answer:

a = -4

b = 3

c = -10

d = -6

Step-by-step explanation:

Plug each value into the equation and solve.

a = 3(0)-4\\a=-4

5=3b-4\\9=3b\\b=3

c=3(-2)-4\\c=-6-4\\c=-10

-22=3d-4\\-18=3d\\d=-6
