Solve the system of equations. \begin{aligned} &-9y+4x - 20=0 \\\\ &-7y+16x-80=0 \end{aligned} −9y+4x−20=0 −7y+16x−80=

bekas [8.4K]

Answer:

(5 , 0)

Step-by-step explanation:

7 * (−9y+4x−20)=0

9 * (−7y+16x−80)=0

-63y + 28x -140 = 0 ......a

-63y + 144x -720 = 0 .....b

b-a: 116x - 580 = 0

116x = 580

x = 5

y = (4x-20)/-9 = 0/-9 = 0
