Solve this system of liner equations.separate the -x and y - values with a comma. 2x=96-14y 9x=40-14y

1 answer:

3 0

A) 2x=96-14y
B) 9x=40-14y
Rearranging algebraically

A) 2x +14y = 96
B) 9x +14y = 40

Multiplying equation A by -1
A) -2x -14y = -96 Then adding it to equation B
B) 9x +14y = 40
7x = -56
x = -8

2*-8 = 96 -14y
-16 -96 = -14y
-112 = -14y
y = 8
