X = 4 y = 3 4x-3y=7 x=13-3y
4(13-3y) -3y =7
52 -12y -3y =7
-15y=-45
-y=-3 y = 3
x=13-(3*3)
x=13-9
x =4

Answer:
20 - 16y
Step-by-step explanation:
Given
5 - 5(2y - 3) - 6y ← distribute parenthesis
= 5 - 10y + 15 - 6y ← collect like terms
= (5 + 15) + (- 10y - 6y)
= 20 + (- 16y)
= 20 - 16y
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (6, - 3)
m =
=
= - 1
