Answer:
B.) There were 15 more questions on the test than the last test.
Step-by-step explanation:
Answer: I got x = 16
hope its helpful......
x = 2
y = 5
3x + y = 11 equation (1)
-x + y = 3 multiply this equation by -1
x - y = -3 equation (2)
by adding 2 equations
4x = 8
by sub. in Equation (2)
2 - y = -3
y = 2+3
it should be (-8, -7)
look up a coordinate plane
