∙ 14y ago2x + 5 = 25 2x = 20x = 10
3x
8x-7 plus 2x equals 6 plus 5x plus 2?
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
2x + 5 = 25 2x = 20x = 10
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
(2,7)
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
x=5
9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
2X + 25 = 7X subtract 2X from each side 25 = 5X divide both sides by 5 5 = X
it equals 13X.
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
x=1
2x + 5x + 25 = 17x + 25 = 1Subtract 25 from each side of the equation:7x = -24Divide each side by 7:x = -24/7That's the only answer there is.
-3x+7=2x-18 ---> 7+18=2x-3x ----> 25=5x ----> x=5
