You need more information to solve for x and y. One answer is x=3 and y=1.
4x+2y = 20 2y = -4x+20 y = -2x+10
If: -4x+2y = 9 Then: 2y = 4x+9 Divide all terms by 2: y = 2x+4.5 which is now in slope intercept form
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
many solutions
2y = 4x + 4y = 2x + 2
4x-y=2, thereforey=4x-2sub y into 3x+2y=6...3x+8x-4=611x=10x=10/11
4x-2y = 10 -2y = -4x+10 y = 2x-5 which is now in slope-intercept form

The process is called "Solve the equation for 'y'."4x - 2y = 6Subtract 4x from each side:-2y = -4x + 6Divide each side by -2 :y = 2x - 3
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
Add 4x to each side: 2y = 4x + 8Divide each side by 2: y = 2x + 4
many solutions
4x + 3y = 4 x - 2y = -10, so add 2y to both sides gives x=2y-10, replace this into first equation gives: 4(2y-10) + 3y = 4, expand that gives 8y-40+3y=4, add 40 to both sides, this gives: 8y + 3y =44, or 11y = 44 giving you y=4. You have solved for y, now solve for x: 4x + 3y = 4, gives 4x +12 = 4, or 4x=-8 giving x=-2. So x=-2 and y=4. QED.
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
