Step-by-step explanation:

I will use elimination for this one, by changing the 2nd equation by a factor of -1, to find y.

Now, substituting the y in the 1st equation, we solve for x.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
