Question

Solve each system of equations.

1. y = -3x - 21
y = 5x + 19

Answer 1

y = -3x - 21 <---e1
y = 5x + 19 <---e2
Use substitution :-)
Plug e1 into e2 since the value of y is given
-3x-21=5x+19
solve for x

Answer 2

ohhh okay thanks!

Answer 3

Did you solve?

Answer 4

yep x = -5, y=-6

Answer 5

@pooja195 i'm actually stuck on this other problme, could you hlep me, it's

5x-4y=-19
x+5y=-27

Answer 6

Im more fimiliar with substituion
x+5y=-27
subtract 5y from both sides now you have
x=-5y-27
now you have 2 equations
5x-4y=-19 <---e1
x=-5y-27 <---e2
Plug e2 into e1 since the value of x is given
5(-5y-27)-4y=-19
and solve for y from there :)

Answer 7

thanks!

Answer 8

yw let me kno wt u get

Answer 9

x= -7
y= -4

Answer 10

Good job :-)
