Solve the system of equation using substitution 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero
Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
How do you solve this equation 3x plus 2y equals 12 solve for y?
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
How do you factor 3xy plus 3y squared?
3xy + 3y2 = 3y (x + y)
Sqrt x-7-5 equals 0?
x = 12
How do you solve -2x-10y-12 and 3x y equals 4?
-2x-10y-12+3xy=4Put all x's to the other side and the ones with y's on the other:-10y+3xy=4+2x+12-10y+3xy=16+2xNow you factor a y from the side with the y's:y(-10+3x)=16+2xDivide both sides by (-10+3x):y=(16+2x)/(-10+3x)
Is y equals 6 a linear function?
yes 3xy=6
Solve the system of equation using substitution 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero
What are M and Y if Y plus y plus y plus equals MY?
M=3 because y+y+y= 3xY and MY= MxY
Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
What is the answer to 12 x plus 16 y equals when x equals 1 and y equals 2?
You plug in the values of x and y and solve 12x + 16y = ? 12(1) + 16(2) = 12 + 32 = 44
How do you solve this equation 3x plus 2y equals 12 solve for y?
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
How do you solve -y plus y?
-y + y equals 0.
What are the factors for 3xy?
1,3,x,y,3x,3y,xy,3xy
What is is 3x times y?
3xy
If 2 plus 2 equals x and x2 equals y and y-x equals a and a plus y equals b what is b?
in order to solve this problem you have to solve for x first wich you are given the data to pre forme so x=4 and x.2=8 and 8=y and y-4=4=a=x so a+8=12 and 12=b
How do you factor 3xy plus 3y squared?
3xy + 3y2 = 3y (x + y)
