5x plus 9y equals 0 6x plus 6y equals 2?
5x + 9y = 06x + 6y = 2 use substitution method5x + 9y = 0y = -5x/96x + 6y = 2 substitute y with -5x/96x + 6(-5x/9) = 26x - 30x/9 = 2 multiply by 9 to both sides54x - 30x = 1824x = 18x = 24/18 = 4/3y = -5x/9 = (-5/9)x substitute x with 4/3y = (-5/9)(4/3) = -20/27Thus the solution is x = 4/3 and y = -20/27.
What is the answer to 5x plus 9y equals 19?
x = 2, y = 1
What does 3y to the 2nd power-9y plus 6?
Assuming this is part of an equation but missing "= 0" and you want the values of y: (3y - 3)(y - 2) are the factors so y = 1 or 2.
What is the solution to the system of equations 3x plus 2y equals 13 and 2x plus 3y equals 12?
2x+3y=12 ......1st equation 3x+2y=13 .......2nd equation ____________________________________ multiplying 1stt equation by 3 and 2nd equation by 2 3x(2x+3y=12) 2x(3x+2y=13) _______________________________ now the equations become 6x+9y=36 ...3rd 6x+4y=26 ....4th by solving both equation(substractinf 4th from 3rd) we get.. 5y=10 therefore y=2 and x=3
What are the intercepts for the equation 18x-9y plus 3z equals 18?
18x - 9y + 3z = 18First, just to clean it up a bit, divide both sides of the equation by 3.(This doesn't change the equation or its graph in any way.)6x - 3y + z = 6At the 'x'-intercept, 'y' and 'z' are zero:6x = 6x = 1At the 'y'-intercept, 'x' and 'z' are zero:-3y = 6-y = 2y = -2At the 'z'-intercept, 'x' and 'y' are zero:z = 6
9y-3y plus 2y equals?
9y-3y=6y; 6y+2y=8y; so your answer is 8y
25x plus 12y plus 3z-15x-3y plus 4z equals?
its 10x +9y +1z
What does 8x - 6 plus 5x plus 3y - 12y - 4 equals?
13x - 9y - 10
What does 12y plus 3 equals 9y-15 equal?
12y+3=9y-15 3y=-18 y=-6
Solve the equation10y equals 6y plus 5 plus 3y?
10y= 6y+5+3y 10y=6+9y y=6
What is 3y - 6 equals 9y?
y = -1
How do you Factor a²-x²-9y² plus 6xy?
(a + x - 3y)(a - x + 3y)
What is the relationship 3x - 3y equals -9 and 9x - 9y equals -27?
3x-3y=-9 and 9x-9y=-27 both simplifies to x-y=-3.
What is 2x plus 3y plus 4x plus 9y?
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
What value of b will make 2x-3y equals 5 and 9y plus bx equals 4 parallel?
2x - 3y = 5 => 3y = 2x - 5 has a gradient of 2/3 9y + bx = 4 => 9y = -bx + 4 has a gradient of -b/9 The two gradiends must be the same if the two lines are parallel: 2/3 = -b/9 so that b = -6
What is 6x plus 3y plus 6y-2x?
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
7x plus 3y equals fourteen and 5x plus 9y equals ten What is the value of x and y?
7x + 3y = 14 5x + 9y = 10 __________ (subtract bottom from top) 2x -6y = 4, therefore 2x = 4 + 6y, therefore x = 2 + 3y Insert x = 2 + 3y into the original equation and calculate 7(2 + 3y) +3y = 14 14 + 21y +3y = 14 24y = 0 y = 0 If y= 0, then x = 2 FINAL ANSWER!
