First, we would want to combine like terms. So, we should combine 7x and 3x by subtracting them.7x + 14 – 3x = 304x + 14 = 30Subtract 14 from both sides; whatever you do to the left you must do to the right4x = 16Divide by 4x = 4 Log in to Reply

First, we would want to combine like terms. So, we should combine 7x and 3x by subtracting them.

7x + 14 – 3x = 30

4x + 14 = 30

Subtract 14 from both sides; whatever you do to the left you must do to the right

4x = 16

Divide by 4

x = 4

X=4, hope this helps 🙂
