Question

11x+15y+23=0 and 7x-2y-20 =0 find the answer by substitution method

Answer 1

Answer:

y=-3,x=2

Step-by-step explanation:

11x+15y+23=0 eq1. ,7x-2y-20=0 eq2

11x=-15y-23

x=-15y-23/11 eq3

putting the value of x in eq 2

7(-15y-23/11)-2y=20

-105y-161-22y=220

-127y=220+161

y=381/-127

y=-3

putting the value of y in eq 3

x=-15(-3)-23/11

x=45-23/11

x=-22/11

x=2
