What is the elimination method for

x + y = -1
x - y = 19

x=9, y=-10. (9, -10).

Step-by-step explanation:

x+y=-1

x-y=19

2x=18

x=18/2

x=9

9-y=19

y=9-19=-10

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

=
