Question

solve the following pair of linear equation by the substitution method 8 x + 5 Y is equal to 9 and 3 X + 2 Y is equals to 4​

Answer 1

Answer:

Step-by-step explanation:

substitution method.....

x=(9-5y)÷8...............(1)

then

3((9-5y)÷8)+2y =4......

then solve these equation  

we get  

x =-2  

then y = {-18=9-5y} thus y =5

hope it will help u

Answer 2

8x+5y=9

x=9-5y^8

puting this in 3x+2y=4

3(9-5y^8)+2y-4=0

27-15y+16y-32=0

y-5=0

y=5

puting y=5 in x=9-5y^8

x=9-5(5)^8

x=9-25^8

x=-16^8

x=-2
