Your photo is super blurry! I can’t read parts of the problems, so I can’t exactly help you. Sorry! Good luck.
Answer:
n=o
Step-by-step explanation:
2 days late, but the answer is no solution. solving a system of equations means finding where they intersect, but by looking at these equations, you know that they never intersect--they're parallel.
they share a slope (2), making them either parallel or "the same line", but the different x-intercepts (9 and -9) mean that they're different lines. they have no solution, or no intersection point, because they're parallel lines.
Answer:
x=w-z
add x to both sides w=z+x
subtract z from both sides w-z=x
X=-b/2a=4/14=2/7
Plug this value back into the function to find the corresponding Y value
