8x = 6y
(8/6)x = y
(4/3)x = y
Let x = 3, 6, and 9, then y = 4, 8, and 12. So that for any value of x, you will find a correspoinding value for y.

What is the x value of -8x plus 8x plus 4 equals -24?
- 8x + 8x = 0 so question is meaningless.
Given ABCD and equals 55 and equals 8x plus 7. what is the value of x?
X=6
Evaluate 8x for each value of x x equals 0.5 x equals 2.3 x equals 0.74?
0.5*8=.40
What is the value of x if 8x plus 5 equals 25?
8x + 5 = 25(- 5 from both sides)8x = 20(divide both sides by 8)x = 2.5
If x equals -3 Andy equals 6 and z equals 8 what is 6y over x?
x = -3; y = 6; 6y/x = 6(6)/-3 = 36/-3 = -12
8x-6y equals 18 and 4x-6y equals 6?
8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1
What is the slope-intercept form of 8x-6y equals 48?
slope intercept form y = mx + b 8x-6y = 48 -6y = -8x + 48 y = (-4/3)x + 8
3x plus 6y equals 48 -5x plus 6y equals 32?
Presumably this is a simultaneous equation question in the form of: 3x+6y = 48 -5x+6y = 32 Subtract the bottom equation from the top equation in order to eliminate y. Note that 3x - - 5x is equal to + 8x: 8x = 16 Divide both sides by 8 to find the value of x: x = 2 Substitute the value of x into the original equations to find the value y: Therefore: x = 2 and y = 7
4x plus 2y equals -12 8x plus 6y equals -4?
x = -8, y = 10
Is this pair of lines parallel 3x-4y equals -3 and 8x plus 6y equals 14?
Put in this form to see. Y = mX + c 3X - 4Y = - 3 - 4Y = - 3X - 3 Y = (3/4)X + 3/4 --------------------- 8X + 6Y = 14 6Y = - 8X + 14 Y = (- 4/3)X + 7/3 ----------------------- Closer to perpendicular than anywhere near parallel!
Solve by the elimination method x plus 6y equals 19 -x plus 6y equals 17?
(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.
What is x equals 4y-2 and x equals 6y plus 8?
By definition: 4y-2 = 6y+8 4y-6y = 8+2 -2y = 10 y = -5 and by substituting this value into the equation x = -22
What is the x value of -8x plus 8x plus 4 equals -24?
- 8x + 8x = 0 so question is meaningless.
Given ABCD and equals 55 and equals 8x plus 7. what is the value of x?
X=6
What does y equal in this equation 8x plus 6y equals 16 4x-2y equals 8?
x = 2, and y = 0. Here's one way to solve:Multiply the second equation (both sides) by 3, then add the two equations:8x + 6y = 1612x - 6y = 24----------20x = 40 ----> x = 2, then substitute x=2 into one of the original equations:8*2 + 6y = 16 --> 6y = 0, and y=0. Check with the other equation: 4*2 - 2y = 8 ---> -2y = 0, and y = 0.
