What is 4x plus 12-5x-30?
4x+12-5x-30=-x-18
What is 4x equals 120?
If 4x=120, x=30.
What is 4x plus 8y equals 20 - -4x plus 2y equals -30?
It looks like you have 2 simultaneous equations with 2 variables:4x + 8y = 20 and -4x + 2y = -30. Solution is {x=7, y = -1}.One way to solve:Add the two equations together, combining like terms: (4x - 4x) + (8y + 2y) = 20-30 --> 0 + 10y = -10 --> y = -1. Substitute this into either of the original equations and solve for x=7, then check in the other equation to make sure you calculated correctly.
4x plus 6 equals 30 what does x stand for?
Gosh... 4X plus 6 equals 30... This concludes to: 4X= 4 x X All you have to do is work back wards!!!! I'm only in year 6!! 30-6=24 Which mean 4 x X=24 X=6!!!!!!!!! =D
What is the answer to 4x-7-2x 5?
Well take your pick either 4x-7 = -28 .... -28 -2 = -30 .... -30x5 = -150 or 4x-7 = -28 .... (-2x5=-10) .... -28-10 = -38
8x plus 30 equals 4x plus 18 solve for x?
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
What are the solutions for 4x2 - 30 equals 34?
4x² - 30 = 34 4x² = 34 + 30 4x² = 64 4x = √64 4x = 8 x = 8 ÷ 4 x = 2
5x plus 20 equals 4x plus 30?
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
What is 4x plus 12-5x-30?
4x+12-5x-30=-x-18
What is 4x equals 120?
If 4x=120, x=30.
What does x equal in 2x plus 6-6x equals 30?
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
How do you graph 5x-6y equals -30?
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
How do you find the y-intercept of the line 4x plus 5y equals 30?
4x+5y = 30 5y = -4x+30 y = -4/5x+6 in slope intercept form So the y intercept is 6.
4x plus 69 equals 30 plus 5x solve for x?
4x + 69 = 30 + 5xSeparate the variables and constants (subtract 4x from each side):69 = 30 + xSubtract 30 from each side (your variable is already a unit) :39 = x
8x2 - 14x - 30 by 2x - 6?
( 8x2 - 14x - 30 ) divided by ( 2x - 6 ) = 4x + 5
How do you solve -21-4x equals 9-7x?
-21-4x=9-7x 7x-4x=9+21 3x=30 x=30 / 3 therefore x=10
What is the answer to 4x plus 6x equals 30?
4x+6x=30 is the same as: 10x=30 so we divide by 10 and get: x=3 (I do not see how this relates to calculus, but O.K.)
