What else can I help you with?
If x equals 3 and y equals 2 then 7x plus 5y equals?
7x + 5y 7(3) + 5(2) 21 + 10 = 31
4x plus 5y equals 2 7x minus 2y equals 1 solve by substitution?
4x + 5y = 2 and 7x - 2y = 1 From the first equation, x = (2 - 5y)/4 putting this value of x to the second equation, 7(2 - 5y)/4 - 2y =1 => (14 - 35y)/4 - 2y = 1 =>14 - 35y - 8y = 4 =>14 - 43y = 4 =>43y = 10 => y = 10/43 putting y = 10/43 in x = (2 - 5y)/4 => x =( 86 - 50 )/172 => x = 36/172 => x = 9/43 therefore, x = 9/43 and y = 10/43
What is the answer to 3X plus 2Y equals -26 and 4X minus 5Y equals -4?
X = -2(13 + y) / 3x = 5y / 4 - 1
5y plus 4 - 2y equals 9?
5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3
How do you solve 7x-2 equals x plus 4?
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
What is the solution for 10x-5y equals -20 and 7x-5y equals -20?
x = 0 and y = 4
If x equals 3 and y equals 2 then 7x plus 5y equals?
7x + 5y 7(3) + 5(2) 21 + 10 = 31
What are the solutions to the equations 7x-4y equals 13 and 2x-5y equals -4?
It works out that the solutions are: x = 3 and y = 2
Solve for y 5y equals 7x plus 17?
24
7x plus 5y equals 2 8x - 9y equals 17?
(1, -1)
What is the order pair for the matrice equation 7x-4y equals 13 and 2x-5y equals -4?
It works out that: x = 3 and y = 2
Are 5x-7y equals 6 and 5y-7x equals 4 perpendicular?
No, because a slope needs to be negative and opposite the other slope to be perpendicular and in this problem it is not.
What is the answer to 8-5y equals 12?
8 - 5y = 12 -5y = 4 y = -4/5
What is the value of x if 4x equals 5y?
If: 4x = 5y Then: x = 5y/4
Rewrite the given equation in slope intercept form. 7x plus 5y-35 equals 0?
69
4x plus 5y equals 2 7x minus 2y equals 1 solve by substitution?
4x + 5y = 2 and 7x - 2y = 1 From the first equation, x = (2 - 5y)/4 putting this value of x to the second equation, 7(2 - 5y)/4 - 2y =1 => (14 - 35y)/4 - 2y = 1 =>14 - 35y - 8y = 4 =>14 - 43y = 4 =>43y = 10 => y = 10/43 putting y = 10/43 in x = (2 - 5y)/4 => x =( 86 - 50 )/172 => x = 36/172 => x = 9/43 therefore, x = 9/43 and y = 10/43
What is the answer to 7x-4 equals 60?
7x - 4 = 60 7x = 64 x = 9.14
