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
