Answer:
x = [tex]\frac{-212}{3}[/tex]
y = 24
Step-by-step explanation:
-3x - 8y = 20 .... (1)
-5x + y = 19 .... (2)
What we can do is take the (2) equation
-5x + y = 19
and solve for y by adding 5x to both sides
y = 24
now that we have y we substitute it in for y in equation (1)
-3x - 8(24) = 20
-3x - 192 = 20
we want to solve for x so we need to get its self.
add 192 to both sides
-3x = 212
now we divide both sides by -3. It's going to be a fraction.
x = [tex]\frac{-212}{3}[/tex]
Answer:
x=-4
y=-1
Step-by-step explanation:
-3x-8y=20
-5x+y=19
rewrite for y:
y=19+5x
substitute y
-3x-8(19+5x)=20
-3x-152-40x=20
-3x-152-40x+152=20+152
-43x=172
-43x/-43=172/-43
x=-4
substitute x
-5(-4)+y=19
20+y=19
y=-1
check:
-3(-4)-8(-1)=20
12+8=20
-5(-4)+-1=19
20-1=19
