Question

Please Solve Simultaneous Equasion

2y+x=4
3y-2x=13

Answer 1

do i have to show u ?

Answer 2

In the first equation, isolate x. Then, plug that value into the x value of the second equation to find y. With the y value, you can find x by plugging it into either of the equations assuming that this is a system of equations.

Answer 3

2y + x=4
x = 4 - 2y 1st eq

then replace the value in second equation
3y - 8 + 4y =13
7y=21
y=3

then again replace this valuein 1st eq
x = 4 -6
x =-2

Answer 4

2y + x = 4 ; multiply by 2
3y -2x = 13


4y +2x = 8
3y -2x = 13 ; now add together
------------
7y + 0 = 21

7y = 21 ; solve for y and use it to solve for x
