What is 5y equals 9 plus 2y equals?
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3
What is 4x plus 3y plus x equals?
5x+3y
5y - 4 plus 3y equals 12?
5y - 4 + 3y = 12 Combine like terms: 8y - 4 = 12 Add 4 to both sides: 8y = 16 Divide both sides by 8: y = 2
What is the answer for 9X 5Y - 3X - 8Y?
6x-3y
What is x and y in 3x plus 3y equals 17.7 and 2x plus 3y equals 15.55?
x = 2.15 and y = 3.75
4x-5y equals 20 equals x-3y equals 10?
4x-5y=20 x-3y=10 becomes x=3y-10 plug that into the first equation: 4(3y-10)-5y=20 12y-40-5y=20 7y=60 y=60/7 If x=3y-10, then x=3(60/7)-10 x=180/7 - 70/7 x=110/7
X over 5y plus 2x over 3y equals?
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
Solve the system of equations -x minus 3y equals -4 and 3x plus 5y equals 16?
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
How do you solve the equation 5y equals 3Y plus 12?
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
5y - 2y equals 3y plus 2 what is the answer?
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
What is the answer to -2 equals 3y-18-5y?
-2 = 3y-18-5y 16=3y-5y 16=-2y y=-8
What is 2X plus 3Y-X plus 5Y?
2x + 3y - x + 5y combine the like terms 2x - x + 3y +5y simple arithmetic x + 8y
What is 4x 3y -5x 2y?
I understand this to be 4x + 3y - 5x + 2y. -x + 5y
4x-3y equals 11 3x-5y equals -11?
no, 4x-3y=11x 3x-5y doesn't equal -11
5y plus 14 plus y equals 3y-7?
5y+14+y = 3y-7 5y+y-3y = -7-14 3y = -21 y = -7
What is the ordered pair the is th solution to these equations x equals 5y and 2x - 3y equals 14?
(10, 2)
What is -6x plus 3y equals -18 -10 plus 5y equals -30 using substitution?
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
