Question

What is the solution of the system defined by y = -x + 5 and 5x + 2y = 14?

Ax=1/3, y=11/7
Bx=4/3, y=11/3
Cx=5/11,y=0
Dx=4/3,y=1

Answer 1

the answer is c i think

Answer 2

y = -x + 5
5x + 2y = 14

5x + 2(-x+5) = 14
5x - 2x + 10 = 14
3x = 14 - 10
3x = 4
x = 4/3 or 1 1/3

y = -x + 5
y = -4/3 + 5
y = -4/3 + (5 * 3/3)
y = -4/3 + 15/3
y = -4+15 / 3
y = 11/3 or 3 2/3

Correct answer is B. x = 4/3 ; y = 11/3
