Question

Solve the system of linear equations by substitution: (SHOW UR WORK) y=5x-6 y=4x-2

Answer 1

Answer:

x = 4

y = 2

Step-by-step explanation:

1) y = 5x - 6

2) y = 4x - 2

sub 1 into 2

5x - 6 = 4x - 2

5x - 4x = 6 - 2

x = 4 ---> (3)

sub 3 into 2

y = (4 * 1) - 2

y = 4 - 2

y = 2

Answer 2

Answer:

4

Step-by-step explanation:

Since they both equal y, they are both equivinlent

$5x-6=4x-2$

$5x=4x+4$

$x=4$

CHECK

$20-6=16-2$

$14=14$
