Answer:
Step-by-step explanation:
Graph can be plotted by substituting value of x and finding value of y .
3x-5y+4=0 -----------(1)
If x=1 , y = 7/5 if x = 2 , y = 2
9x+15y+12=0 -----------(2)
If x=1 , y = -7/5 if x = 2 , y = -2
To solve the equations follow the steps below:
Multiply (1) by 3
9x-15y+12 =0 -----------(3)
(3) + (2)
18x+24 = 0
x= -24/18 = -4/3
From 1
3(-4/3) - 5y + 4 =0
-5y = 3(4/3)-4 = 0
