It is an algebraic expression but if you mean 5x-4y-28 = 0 then it is a straight line equation.

4y -2 = 6 4y = 6 + 2 4y = 8 y = 2
6-2x-8+3+12x+4y 10x+4y+1 Note that - -3 = +3 and that - -4y = +4y
-7y + 4y = -3y
4y-32x = -28
It is an algebraic expression but if you mean 5x-4y-28 = 0 then it is a straight line equation.
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
7y-3y-14=14 4y-14=14 4y-14+14=14+14 (adding 14 on both side) 4y=28 (4y)/4=28/4 (dividing by 4 on both side) y=28/4=7
Does it say solve for y?
4Y - 8 = 20 add 8 to each side 4Y - 8 + 8 = 20 + 8 4Y = 28 divide each sides integers by 4 (4/4)Y = 28/4 Y = 7 ---------------------check in original equation 4(7) - 8 = 20 28 - 8 = 20 20 = 20 checks by equality
4y + 10 = -18 4y = -28 y = -7
7x-4y= 13 3x-y= 7 we have two equations we need to find the y, because it is by him self. and now for finding the y we transpose -y eqaul to 7 -3x then subt to equation 1 7x-4(7-3x)= 13 7x -28 + 12x= 13 combine like terme 7x +12x -28 =13 19x -28 = 13 +28 +28 19x= 41 19x/19 = 41/19 x= 2.15 now find the y 7(2.15) - 4y= 13 15.0.5 -4y = 13 -15.05 -15.05 -4y=-2.05 -4y /-4 y=-0.5125 the solution is ( 2.15, 0.5125)
(12, 1)
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3
4y + 8y = 12y 4y - 8y = -4y 4y x 8y = 32y2 4y/8y = 1/2
