Question

Solve the simuteneous equation
4x+2y=6
x-2y=9​

Answer 1

find the same x-value and the same y-value that satisfies both ... 1 2 3. + 4 5 6. 5 7 9 ... + (4x – 2y + 9 = 0).

Explanation:

Answer 2

x=3 y= -3

Explanation:

Add the two equations to eliminate y

4x+2y=6

x-2y=9​

-------------

5x = 15

Divide by 5

5x/5 = 15/5

x = 3

Now find y

x - 2y = 9

3 -2y = 9

Subtract 3 from each side

3-2y-3 = 9-3

-2y = 6

Divide by -2

-2y/-2 = 6/-2

y = -3
