Not sure about slove, but to solve it:
first combine like terms: 5x + 9 = 30
Then subtract 9 from both sides: 5x = 21
Finally, divide both sides by 5: x = 21/5 = 4.2

How to slove 4x plus 7 31?
The math problem 4x plus 7 times 31 equals 8. This is taught in math.
8x plus 30 equals 4x plus 18?
subtracting gives 4x = -12 so x = -3
What is the x and y coordinates of these equations y equals 3x and 4x plus 2y equals 30?
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
How do you slove 3x plus 1 plus 4x-5 equals 31?
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
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
How to slove 4x plus 7 31?
The math problem 4x plus 7 times 31 equals 8. This is taught in math.
5x plus 20 equals 4x plus 30?
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
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
8x plus 30 equals 4x plus 18?
subtracting gives 4x = -12 so x = -3
What does x equal in 2x plus 6-6x equals 30?
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
What is the x and y coordinates of these equations y equals 3x and 4x plus 2y equals 30?
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
How do you slove 3x plus 1 plus 4x-5 equals 31?

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
-y equals 4x plus 1 4x plus y equals 2?
2
4x plus 5 equals -19 equals?
4x-14
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.)
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
