-9y plus 8 equals -91?
-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
What is the answer to 5x - 4y plus 9y plus x -9 plus 7?
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
What is 4x plus 6x plus 6x plus 9?
16x+9 without the rest of the equation, what this equals, I can't solve
What does 9y to the 4th power times y to the fifth power equals to?
9Y^4 * Y^5 add exponents and coefficients multiplied 9Y^9
Can you solve the cryptogram AB plus BA plus B equals AAB?
A = 1, B = 9
2y plus 9y plus 9 equals?
well we can't simiply solve that problem. we must no what y= to solve this. So u can only simpify ok combine like terms. 2y plus 9y is 11y. your answer is 11y+9
What is the slope-intercept form of 9 plus 9y equals 27x?
9 + 9y = 27x -9 -9 9y = 27x - 9 9y/9 = 27x/9 - 9/9 y = 3x -1
How do you solve this type of reasioning such as 92y equals 36 then 9y equals?
92y = 36 y = 36/92 = 9/23 Then: 9y = 81/23
9y plus 5 equals 0 what is y?
9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
-9y plus 8 equals -91?
-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
Answer to x plus 9y equals 18?
x=9 y=1
What is the answer to 9y - 9 equals -117?
9y - 9 = -117 9y - 9 + 9 = -117 + 9 9y = -108 9y/9 = -108/9 y= -12
What is 31 equals 4-9y?
y = 3 in the equation 31 = 4 - 9y Solve for y. 31 - 4 = 4 - 9y - 4 Simplify 27 = 9y Divide both sides by 9 to get the term y by itself on one side of the equation. 27 / 9 = 9y / 9 Simplify 3 = y
-3x plus 2y equals 9?
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
How would you solve 6x-3y equals 9 y equals -3x plus 2x?
there are several methods .... elimination, substition, graphing, and cramer's rule for substitution : (1st eq) 6x - 3y = 9 (2nd eq) 9y = -3x + 2x simplifies into 9y = -x or x = -9y substitute this into the (1st eq) 6(-9y) - 3y = 9 -54y - 3y = 9 -57y = 9 y = -9/57 =-3/19 now use this to find the x value ... x = -9y = -9(-3/19) x = 27/19 thus the answer is the ordered pair (27/19, -3/19)
What does y equal if 9y plus 10 equals -8?
9y + 10 = - 8 subtract 10 from both sides 9y = -18 Divide by 9 on both sides y = -2
What is -9y equals -18?
9
