Solve the following system using elimination:
{x - 2 y = -23 | (equation 1)
{x - y = 7 | (equation 2)
Subtract equation 1 from equation 2:
{x - 2 y = -23 | (equation 1)
{0 x+y = 30 | (equation 2)
Add 2 × (equation 2) to equation 1:
{x+0 y = 37 | (equation 1)
{0 x+y = 30 | (equation 2)
Collect results:
Answer: {x = 37 , y = 30
Answer:
the answer is that a=2
Step-by-step explanation:
Answer:
m=rise/sun=y2-y1 x2-x1
Step-by-step explanation:
m=slope (x1, y1) coordinates of first point in the line
(x2, y2) coordinates of second point in line.
The answer is a because you just take the points and switch them
Answer:
13-n=4
Subtract both sides by 13
-n=-9
n=9
Step-by-step explanation:
13 less means - and a number means n that you don’t know. is means = sign. And so we get the answer that I gave you. Thank you
