-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
2x + 5 = -76 - 7x Add 7x to both sides: 9x + 5 = - 76 Subtract 5 from both sides: 9x = -81 Divide both sides by 9: x = -81/9 = -9
7*x - 5 + 14 = 77*x + 9 = 77*x = -2x = -2/7x equals minus two sevenths
It is a linear equation in one variable, x.
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
7x + 5 = 68 subtract 5 from both sides 7x = 63 divide both sides by 7 x = 9
2x + 5 = -76 - 7x Add 7x to both sides: 9x + 5 = - 76 Subtract 5 from both sides: 9x = -81 Divide both sides by 9: x = -81/9 = -9
x=2 because 9-(14)=-5
7*x - 5 + 14 = 77*x + 9 = 77*x = -2x = -2/7x equals minus two sevenths
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
It is a linear equation in one variable, x.
Subtract 7x from each side: 8 = -9 Not possible, game over.
If x=2, then 7x = 14 and if y=5 then 4y=20.
7x = 4x - 93x = -9x = -3
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
