=3x+7
3x+7=4x 7=4x-3x 7=x
3x - 8 = 7 so x = 5
3x+7=4x-73x=(-)7+4x-4x(-)1x=(-)7________(-)1x=7add (-3x) to each side of equation3x +7 = 4x-3x +3x +7 = 4x -3x0 +7= 1x7=x
3x + 7 = x + 13Subtract 7 from each side:3x = x + 6Subtract x from each side:2x = 6Divide each side by 2:x = 3
7x = 3 x = 3/7
(-3x - 1)(3x - 7)
38*4 + 3 + 7 - 3x = 162 - 3x
3x+7=4x 7=4x-3x 7=x
5x+7
13x + 7
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
4x plus 7 plus 3x equals 19 plus xx = 2
In the equation 3x plus 7 equals 13, x is equal to 2.
y = 2x^(2) + 3x + 7 dy/dx = 2(2)x^(2-1) + 3(1)x^(1-1) + 7(0)x^(0-1) dy/dx 4x^(1) + 3x^(0) + 0 dy/dx = 4x + 3(1) dy/dx = 4x + 3 The answer!!!!! I have made a bit of 'heavy weather' of this but only to try and show you how it works out.
3x plus 10x - 7With out knowing what ' x ' actually is.. it will reduce down to.3x + 10 x - 7=13x - 7
4x plus 7
2x3 - 7 + 5x - x3 + 3x - x3 = 8x - 7
