Please help! I will mark you brainliest! Teri incorrectly solved the system of equations below. Identify where the error happened.
2x - 10 y = -30
x - 5y = 20
Step 1:
x - 5y = 20
x = 5y - 20
Step 2:
2(5y + 20) - 10 y = -30
10y + 40 - 10y = -30
40 = -30

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
