Question

2x-y=5 and 3x-4y=10 how to solve this

Answer 1

Answer:

this problem can be solved by elimination method

Explanation:

2x-y=5 multiply this equation by 3

3x-4y=10 multiply this equation by 2

6x-3y= 15 : this is equation 1

6x-8y= 20 : this is equation 2

(-) (+) (-)

= 0 + 5y= -5

y = -5/5

y= -1

put y= -1 in equation 1

6x -3y = 15

6x -3(-1) =15

6x+3=15

6x=15-3

6x=12

x=12/6

x=2

therefore x=2 and y = -1 is your answer

I hope this answer helps you
