Question

Can Someone Solve these & Show The Work Please
Solve the systems using substitution.
6x + 2y = 0
4x + y = -1

3x + 2y = -4
x + 2y = -8

5x - 4y = 14
x - 2y = -2

x + 3y = -4
4x + 5y = 5

x + 3y = -5
2x - y = 18

Answer 1

to start off substitution
2 variables

solve for one variable first

Answer 2

EXAMPLE

X2 + Y2 = 2 SOLVE FOR X USING THIS EQUATION
X3 + Y3 = 3

1/2 [ X2 + Y2 = 2 ]

X + Y = 2
X = - Y + 2 THIS IS WHAT X IS EQUAL TO

X3 + Y3 = 3 USE THE NEXT EQUATION
1/3 [ X3 + Y3 = 3 ]
X + Y = 1
( -Y +2 ) + Y = = 1
|__________|
THIS IS SUBSTITUTED AS X
- Y + Y = 1 -2
0 = - 2 NO REAL NUMBER SOL.

BUT THE PROCESS IS THE SAME
SUBSTITUTION WITH 2 VARIABLES
