Sagot :
Answer:
x-variable
Step-by-step explanation:
When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable. We can eliminate the x-variable by addition of the two equations.
Answer:
1. Y is the variable terminated.
2. X = 1
3. Y = -1
4. (1,0) and (0,-1)
Step-by-step explanation:
After eliminating our Y variable we can solve for X. Our equation for X is 10x=10. After dividing both sides by 10 we get that X=1.
From there we can plug 1 of our previous equations. When we plug 1 in we get that both equations have an equal Y value of -1.
Our solution would be (1,0) and (0,-1)
