Not sure if you mean 7x 6y as in 7*6y=126, where * means "multiplied by" and you must solve for y or if you mean that we must solve for both x and y, but the answer to the part where you are solving 7*6y=126 is 3.

7x-3=39 7x=42 x=6
Solve the equation 7x equals 42?
7x=42 x=42/7 or, x=6
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
How do you solve 7x plus 6 equals -3x minus 24?
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
Use linear combinations to solve the system.. negative 6x plus 8y equals 36 and 7x plus 6y equals 4 Find X and Y?
1. -6x + 8y = 362. 7x + 6y = 46y = 4 - 7xy = (4-7x)/6 Put this in the first equation and solve-6x + 8((4-7x)/6) = 36-36x + 8(4-7x) = 216 Multiply with 6 to simplify.-36x + 32 - 56x = 216-36x -56x = 216 - 32-92x = 184x = 184/-92x = -2X = - 2Now that you have X, put it in any of the equations above to solve Y.7x + 6y = 4 Put in x = -27(-2) + 6y = 4-14 + 6y = 46y = 4 + 14y = 18/6y = 3Y = 3
5x 4y equals 12 7x-6y equals 40?
(4, -2)
5x plus 4y equals 12 7x - 6y equals 40?
(4, -2)
What does 4x plus 6y equals 24 7x plus 6y equals 9?
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
7x plus 3y equals 56 and 6x plus 6y equals 72 What is the ordered pair?

What type of linear system is 7x plus 2y equals 16 -21x-6y equals 24?
Do you mean 7x+2y = 16 and 21x-6y = 24? If so then it is simultaneous equation with the solution being: x = 12/7 and y = 2
Solve for y 7x plus y equals 4?
7x + y = 4y = 4 - 7x
7x plus 2 equals 5.6 solve x?
7x + 2 = 5,6
How do you solve 7x plus 2y equals -3?
Subtract by 7x and divide by 2.
7x-3 equals 39 solve for x?
7x-3=39 7x=42 x=6
