Solve For X And Y:, Y=2+7x, 22122x+6y=172, A. X=30,Y=4, B. X=4,Y=30, C. X=32,Y=226, D. X=221274,Y=4

Solve for x and y:

y=2+7x

−2x+6y=172

a. x=30,y=4
b. x=4,y=30
c. x=32,y=226
d. x=−74,y=4

y = 2 + 7x

-2x + 6y = 172

Use the substitution method

-2x + 6y = 172

-2x + 6(2 + 7x) = 172

-2x + 12 + 42x = 172

40x + 12 = 172

40x = 172 - 12

40x = 160

x = 4

y = 2 + 7x

y = 2 + 7(4)

y = 2 + 28

y = 30

Answer :

B. x = 4, y = 30
