Help asap Solve the simultaneous by the
subtitution method : x + y = 13 and
x -
y = 7

The chosen topic is not meant for use with this type of problem. Try the examples below.

x+y=3, 2x−8y=19

x+2y=4, x−y=−3

2x+y=−2, x+2y=2

Step-by-step explanation:

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
