How do you solve x plus 9y equals 9?
To solve for 2 unknown variables you need 2 independent equations. You have only 1.
If x equals 5 and y equals 2 then 5x plus 9y equals?
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
3x plus 6y equals 5 -6x plus 9y equals 4?
3x + 6y = 5 -6x + 9y = 4 multiply by 2 the first equation 2(3x + 6y = 5) -6x + 9y = 4 6x + 12y = 10 -6x + 9y = 4 add both equations 21y = 14 divide by 21 to both sides y = 14/21 simplify y = 2/3 3x + 6y = 5 replace 2/3 with x 3(2/3) + 6y = 5 2 + 6y = 5 subtract 2 to both sides 6y = 3 divide by 6 to both sides y = 1/2 Thus, the solution point is (1/2, 2/3).
What is -3x 9y-6 in slope intercept form?
If you mean: -3x+9y = -6 then it is y = 1/3x-2/3
What is the solution set of the given equation 4y - 6y plus 9y equals -2?
4y - 6y + 9y = -2Combine like terms on the left side:7y = -2Divide each side by 7:y = -2/7The solution set is: { -2/7 }
X-2y equals o 9y-4x equals 1 substitution method?
x - 2y=0 so x = 2y 9y - 4x=1 Substituting for x, 9y-4*(2y) = 1 or 9y-8y = 1 so that y = 1 then x = 2y = 2*1 = 2
7x plus 5y equals 2 8x - 9y equals 17?
(1, -1)
What is 5x-9y equals 7 7y-3x equals -5?
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
What is the slope-intercept form of -3x plus 9y equals 6?
-3x+9y = 6 9y = 3x+6 y = 1/3x+2/3
What is the answer to 5x plus 9y equals 19?
x = 2, y = 1
What is 9y-11 equals 7?
9y-11=7 +11 +11 9y=18 y=2
What is -9y equals -18?
9
Write 8x-9y equals 2 as a function of y?
The question asks for a function of 'y', so we'll show 'x' as a function of 'y':Given: 8x - 9y = 2Add 9y to each side:8x = 2 + 9yDivide each side by 8:x = 2/8 + 9y/8orx = 1/8 (2 + 9y).==================================================If the questioner actually wants to see it in the more familiar form of [ y = a function of x ],we can massage the original equation around to show that as well.Given: 8x - 9y = 2Subtract 8x from each side:-9y = 2 - 8xMultiply each side by -1:9y = 8x - 2Divide each side by 9:y = 8x/9 - 2/9ory = 1/9 (8x - 2)
How do you solve x plus 9y equals 9?
To solve for 2 unknown variables you need 2 independent equations. You have only 1.
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
How do you solve 6x-5y equals 22 and 9y plus 7 equals 5x plus 8?
1. 6x - 5y = 22 2. 5x - 9y = -1 1 times 5: 30x - 25y = 110 2 times 6: 30x - 54y = -6 Subtract : 29y = 116, so y = 4 and x therefore = 7
The order pair for 4x - 3y equals 2 and 3x plus 5y equals 16?
1: 12x - 9y = 6 2: 12x + 20y = 64 Subtract 1 from 2: 29y = 58 y = 2. So does x.
