Answer:

x = -9/2

Step-by-step explanation:

Substitute y = -6 in the second equation.

y = 4x + 12

-6 = 4x + 12

Subtract 12 from both sides.

-18 = 4x

Divide by 4.

-9/2 = x

HELP Solve for x and PS

ANTONII [103]

Answer:

PS = 84.5 , x = 43.75

Step-by-step explanation:

Since RQ is congruent to PS, PS is 2x - 3

SR: 4x + 1

Extra at the bottom: 4

4x + 1 + 4 = 180

4x + 5 = 180

- 5 - 5

4x = 175

/4 /4

x = 43.75

Plug in for PS

2 (43.75) - 3

87.5 - 3

84.5
