Question

solve the following Simultaneous Equation
4x+3y-4=0 ; 6x=8-5Y.​

Answer 1

Answer:

4x+3y =0 ...(1)

6x+5y=8 ....(2)

multiply equation (1) by 5 and equation (2) by 3

20x+15y=0 ...(3)

18x+15y= 24...(4)

Sub equation (3) and (4)

2x=-24

x=- 12

put x=-12 in equation (1)

4(-12)+3y=0

-48+3y=0

3y=48

y=16

hence ,x=-12 y=16
