Answer:
Step-by-step explanation:
y>x+1
5x-3y=12
2x-y=5
Multiply equation II by 3;
5x-3y=12
6x-3y=15
Subtracting equation II from equation 1;
x=3
2x-y=5
2(3)-y=5
6-y=5
6-5=y
y=1
Answer:
a
Step-by-step explanation:
Answer:
Step-by-step explanation:
Since they both contain 2y we can just subtract the second from the first to eliminate y
4x+2y-3x-2y=6-1
x=5, since 4x+2y=6 we have
4(5)+2y=6
20+2y=6
2y=-14
y=-7
So the solution point (x,y) is (5,-7)
