Question

Solve
2x+y=8,3x-2y=5
​

Answer 1

Answer:

Simultaneous equations:

2x+y=8 -------(1)

3x-2y=5 ------(2)

multiply equation (1) by 2 to get

4x+2y=16 add this to equation (2) this will remove the y's

leaving

7x=21 divide both sides by 7

x=3 now put this vaue of x into either (1) or (2)

we will use (1)

 

2(3)+y=8

6+y=8 subtract 6 from both sides

y=2

so x=3 and y=2

check by plugging these into original equations

2(3)+2=8

6+2=8 correct!

using equation (2)

3(3)-2(2)=5

9-4=5 correct!

Step-by-step explanation:

Answer 2

Answer:

x= 3 ,y =2

Step-by-step explanation:

in the elimination method y= 2 , x= 3
