Well lets see: 2y = 6x+8 y=3x+4 does not equal y=3x+6 So they are not the same.
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
-6
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
-2y=x+8 is the answer
Well lets see: 2y = 6x+8 y=3x+4 does not equal y=3x+6 So they are not the same.
8 + 2y = 6 Subtract 8 from both sides: 2y = -2 Divide both sides by 2: y = -1
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
-6
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
what is c, x + 2y, x+y equal to or greater than 8, x equal to or greater than 3, y equal to or greater than 0.
-2y=x+8 is the answer
That will depend on the plus or minus value of 2y which has not been given or maybe there is an equality sign that is missing.
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
x = 2y = 4
If the two equations are (i) 4x + 2y = 12 and (ii) x + 2y = 6, proceed as follows: Rewrite (ii) as x = 6 - 2y; substitute this expression for x into (i) to result in 4(6 - 2y) + 2y = 12, or 24 - 8 y + 2y = 12, or - 6 y = 12 -24 = -12, or y = -12/-6 = 2. Then, back to (ii) again, x = 6 - 2(2) = 2.
6 + 9 + 8 = 23
