Answer:
Step-by-step explanation:
- 3x-2y =7
- x+2y= -3
- 4x=4
- x=4/4
- x=1
- 3x-2y=7
- 3(1)-2y=7
- 3-2y=7
- -2y=7-3
- -2y=4
- 2y=-4
- y=-4/2
- y= -2
- Verify solution
- x+2y= -3
- 1+2y= -3
- 2y=-3-1
- 2y= -4
- y= -4/2
- y= -2

5. Combining like terms is similar to adding and subtracting whole numbers because you just add/subtract the numbers with the same variables. It's different because in normal adding and subtracting, you can do it with any whole numbers. But with combining like terms you have to make sure that each term has the same variable or else you can't add/subtract them.
