Question

what are the values of X and Y for the following system of linear equation: 8x+5y & 3x+2y =4
a) 2 & -5
b) -5 & 2
c) -2 & 5
d) 5 & 2​

Answer 1

Answer:

option (c)-2&5

Step-by-step explanation:

8x+5y&3x+2y=4

Answer 2

Answer:

8x+5y eqn1› 3x+2y eqn2›

8x+5y *3 3x +2y *8

24x+15y 24x+16y

eqn1 - eqn2

24x+15y

24x+16y

-------------

-1y

put the y value of eqn1

8x+5y

8x+5(-1)

8x-5

x= -5/8
