Solve the equation mathematically 3x -2y =4 and 5x -2y =0
Answers
Answer:
Step-by-step explanation: 3x-2y=4 ------(i)
5x-2y=0 ------(ii)
from equ 1: 3x=4+2y
x= 4+2y /3
put 4+2y/3 into equ 2 in place of x
5(4+2y/3) - 2y =0
20+10y/3 - 2y=0
20+10y/3 =2y
cross multiply
20+10y=6y
10y-6y= -20
4y = -20
y= -5
put y= -5 into equ 3 :3x=4+2y
3x=4+2(-5)
3x=4-10
3x=-6
x=-2
therefore x= -2 and y= -5.
