Please help, I will give brainliest, I am struggling badly.

x+y=2

2x-y=10

Step-by-step explanation:

Lets plug in the values of x and y to see if it matches up.

(4)+(-2)=2

2(4)-(-2)=8+2=10

So the third answer is correct.

Hope this helps!

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
