This is poorly typed, so I will assume you mean "what does 76 * 9 * 9 equal?"
This can be done with a calculator or by hand. (* = multiplied by)
By hand you would simply do long multiplication of 76 * 81 (since you should know that 9 squared is 81)
Note that on each line, everything in bold represents the same number (which equals 5670) and everything in italics represents the same number (which equals 486)
76 * 9 * 9 = 76 * 81
= (70 * 81) + (6 * 81)
= ((70 * 80) + (70 * 1)) + ((6 * 80) + (6 * 1))
= (5600 + 70) + (480 + 6)
= 5670 + 486
= 6156

-6-6x equals 9-9x what is x equal to?
it's an easy one :)-6 - 6x = 9 - 9x-6x + 9x = 9 + 63x = 15x = 15/3X = 5
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
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 6x X 9x?
6x * 9x = 6 * 9 * x * x = (6*9)*(x*x) = 54*x2

-6-6x equals 9-9x what is x equal to?
it's an easy one :)-6 - 6x = 9 - 9x-6x + 9x = 9 + 63x = 15x = 15/3X = 5
What is 9x plus 6 equals 6x plus 15?
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
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
What is 3x plus 6x plus 1 equals 10?
3x + 6x +1 = 10 9x = 10 - 1 9x = 9 x = 1
6x plus 11 equals 92-3x?
6x+11=92-3x +3x +3x 9x+11=92 -11 -11 9x=81 divide by 9 x=9
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 6x X 9x?
6x * 9x = 6 * 9 * x * x = (6*9)*(x*x) = 54*x2
What is 9-x equals 7?

What is X if X -9 equals 6X plus 7?
If: x-9 = 6x+7 then x works out as -3.2
What is 9x - 7 equals 6?
9X - 7 = 6 add 7 to each side 9x - 7 + 7 = 6 + 7 9X = 13 divide both sides integers by 9 (9/9)X = 13/9 X = 13/9 =========check in original equation 9(13/9) - 7 = 6 13 - 7 = 6 6 = 6 --------checks
What is the x and y intercept for 6x-2y equals 18?
Get in form first.6X - 2Y = 18- 2Y = - 6X + 18Y = 3X - 9====================zero out Y to find X intercept3X - 9 = 03X = 9X = 3==========X intercept
3x plus 7 equals 6x - 2?
3x + 7 = 6x - 2 Rearranging gives 6x - 3x = 7 + 2 3x = 9 x = 3
