12 to 14=2
14 to 18=4
18 to 26=8
26 to 42=16
The difference between each number doubles each time.
Therefore the next 2 numbers should be 74 and 138.
16x2=32, 42+32=74
32x2=64, 74+64=138

I need help solving 7-3x=x-2(2+x)

Answer:

x = 5.5

Step-by-step explanation:

First, you need to distribute the -2:

-2(2+x) = -2x-4

Next you simplify:

x-2x = -x

Then you get all the x values on one side of the equation and everything else on the other side:

7-3x = -x-4 --> 11 = 2x
