Answer 2

Answer:

Point of intersection is (-1.5,2.5)

Step-by-step explanation:

L1: x+3y-6= 0--------Eq(1)

L2: y-3x-7=0----------Eq(2)

Now Multiply Equation 1 by 3

3x+9y-18 = 0 -----------Eq(3)

Now add equation 2 and 3

y-3x-7+3x+9y-18=0

10y-25=0

10y=25

y=2.5

-3x+2.5 = 7

hence 3x= 2.5-7 = -4.5

therefore x= -4.5/3 = -1.5
