What else can I help you with?
How can you get coefficients that are equal for y. 3x plus 5y equals 7 2x plus 15y equals 11?
Multiply the first equation by 3 to give 9x + 15y = 21
If x equals 10 and y equals 10 then 9x plus 8y equals?
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
What is 9x plus 27 equals -81?
9x+27 = -81 9x = -81-27 9x = -108 x = -12
Find slope for 5y equals 160 plus 9x?
First write it out. 5y=9x+160 To get it into slope form, it must become the form y=mx+b. In other words, y must be by itself, so you divide every number by 5. It becomes: y=9/5x+32. So the slope is 9/5.
X plus 20 plus 10x equals 20 plus 9x x equals?
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
What is 2x plus 5y plus 9x?
11x + 5y
The order pair for 3x plus 5y equals 21 and -9x plus 4y equals -6?
x = 2, y = 3
What is the elimination method for 11x equals 5y plus 80 and 9x-15y equals 120?
A: 11x = 5y + 80 B: 9x - 15y = 120 A: 11x - 5y = 80 B: 9x - 15y = 120 A: 11x - 5y = 80 B: 3x - 5y = 40 A - B: 8x = 40 x = 5 Now we can plug that value of x into one of the original equations to solve for y: 11(5) - 5y = 80 55 - 5y = 80 -5y = 25 y = -5
3x plus 5y equals 21 -9x plus 4y equals -6?
Multiply first equation by 3: 9x + 15y = 63Add that and second equation: 19y = 57Divide by 19: y = 3, so x = 2
What expresssion represents the sum of (7x-3y) and (2x plus 5y)?
(7x-3y) + (2x+5y) = 9x+2y
How can you get coefficients that are equal for y. 3x plus 5y equals 7 2x plus 15y equals 11?
Multiply the first equation by 3 to give 9x + 15y = 21
What is '6x-5y-2x-3y plus 9x-y'?
86
What is the equation inverse of fx equals 5x-1 divided by 9?
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
What expression is equivalent to 7x plus 4y - 9x plus 5y?
It can be simplified to: 9y-2x
What is the slope in the equation 9x 5y-50?
Without an equality sign and not knowing the plus or minus value of 5y it is not an equation.
2X plus 2X plus 9X equals?
it equals 13X.
What is the slope of 9y plus 9x plus 7 equals 8 plus 9x?
The slope is 0.
