Question

Help me solve using elimination method?
2x - 5y = 7
3x - 10y = 13

Answer 1

label the equations

2x - 5y = 7 .......(1)
3x - 10y = 13 ...(2)

to eliminate y multiply equation (1) by -2 and add to equation 2

-4x + 10y = -14
3x - 10y = 13
----------------
-x = -1


divide both sides by -1 to find x....

now substitute your answer for x into either equation to find y

hope it helps

Answer 2

2x-5y=73-10y=13
2x-5y+5y=73x-10y+5y
2x=73x-5y
2x-2x=73x-2x-5y
71x-5y=13
i think that is right
