Question

2x-3y=7,5x+2y=10 solve by elimination method

Answer 1

Answer:

y=3x+3

Step-by-step explanation:

2x-3y=7,5x+2y=10

3y-2y=5x-2x+10-7

y=3x+3

Answer 2

Answer:

2x-3y=7

2x=7+3y

x=7+3y/2

Put value of x in equation

5x+2y=10

5(7+3y/2)+2y=10

35+15y/2+ 2y=10

35+15y + 2y=10*2

35+17y=20

17y=20-35

y= -15/17

now put value of y in equation

2x-3y=7

2x-3(-15/17)=7

2x+45/17=7

2x+45=7*17

2x+45= 119

2x= 119-45

x= 74/2

x= 37
