What is 6x 24?
24 ; Identify the variable in the equation.5 + 9x = 68a. 5 b. 68 c. x d. 9x
9x plus 4 equals x-7?
9x+4 =x-7 8x=-3 x=-3/8
What is 9x-3(x plus 13y)?
9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
What is x when 9x plus 7 equals 6x plus 25?
If: 9x+7 = 6x+25 Then: x = 6
What is 9x plus 8 equals 6x plus 20?
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
What is 6x plus 3x plus 8 equals 35?
That is an equation.Oh, you wanted to know for which values of x that equation is true? Okay...6x + 3x + 8 = 35⇔ (6x + 3x) + 8 = 35⇔ 9x + 8 = 35⇔ 9x + 8 - 8 = 35 - 8⇔ 9x + 0 = 27⇔ 9x = 27⇔ 9x / 9 = 27 / 9⇔ x = 27 / 9⇔ x = 3
What is the answer to 9x-19 equals 6x plus 2?
9x-19=6x+2 so 3x=21 and x=7
How do you solve 6x plus 18 plus 9x-25?
you just add 6x+9x to get 15x then minus 25 from 18 to get -7 thus the answer will be 15x-7
Find the slope -9x-7y equals 8 the slope is?
In order to find the slope of your line, we must first get it into y=mx+b.-9x-7y = 8-9x + 9x - 7y = 8- 7y = 9x + 8-7y/7 = 9x/7 + 8/7-y = 9x/7 + 8/7(-1) -y = 9x/7 + 8/7y = -9x/7 - 8/7The slope is -9/7 and the y-intercept is -8/7
Factorise 6x plus 9x cubed?
6x + 9x^3 = 3x*(2 + 3x^2)
How do you solve 6x-4y equals 54 -9x plus 2y equals -69 using substitution?
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
