Find the solution of this system of equations. separate the x- and y- values with a comma.
2 answers:
X - 2y = -29
x - y = -11
first solve for x in the first equation;
x = 2y - 29
now substitute it into the second equation;
x - y = -11
2y - 29 - y = -11
y - 29 = -11
solve for y;
y - 29 = -11
y = -11 + 29
y = 18
solve for x by substituting what y equals;
x = 2y - 29
x = 2(18) - 29
x = 7
so your answer is, (7, 18)
hope this helped!! blessings x
x-2y = -29
x-y = -11
we can solve for x in the second equation by adding y to both sides
x= -11 + y
now we can plug this in for the x value in the first equation to solve for y
-11 + y -2y = -29
-11-y=-29
-y= -18
y =18
now that we know what y is equal to, we can plug it in to either equation to solve for x
x-18= -11
x = 7
7 , 18
hope this helped

Answer:

Fractions are sometimes the same as dividing, for this case, that rule applies.

↑ These improper fractions translate to...

A
Lines that are parallel have the same slope number next to X
Y= 5x+9
5 is the slope and 9 is the y intercept

M + t = 26
m = t - 6
t - 6 + t = 26
2t - 6 = 26
2t = 26 + 6
2t = 32
t = 32/2
t = 16 <== Trevor has 16
m = t - 6
m = 16 - 6
m = 10...and Marissa has 10
