(−112, −263 )

(−14, 1 )

(54, 3 )

(72, 6 )

Answer 1

Answer:

so the answer is

D. (7/2, 6)

Step-by-step explanation:

The question was wrong, but I will still answer it:

Steps: Solve x = 1/4y + 2 for x:

x = 1/4y + 2

Steps: Substitute 1/4y + 2 for x in -4x + 3y = 4

−4x + 3y = 4

-4 (1/4y + 2) + 3y = 4

2y − 8 = 4 (Simplify both sides of the equation)

2y − 8 + 8 = 4 + 8 (Add 8 to both sides)

2y = 12

2y/2 = 12/2 (Divide both sides by 2)

y = 6

Steps: Substitute 6 for y in x = 1/4y + 2:

x = 1/4y + 2
x = 1/4(6) + 2

x = 7/2 (Simplify both sides of the equation)

so the answer is :

x = 7/2 and y = 6
