The "answer" is a pair of two numbers ... a number for 'x' and a number for 'y' ...
that make the equation a true statement.
There are an infinite number of answers. You can pick any number out of the blue
for 'x', and then use the equation to find out the 'y' that goes with it. Every pair
you build this way is an 'answer' to the equation.
If you draw the graph of this equation, you get a straight line with no ends. Every
point on the line is an 'answer' to the equation, (and you can imagine how many
points there are on a line with no ends).

If x equals 10 and y equals 8 then 7x plus 8y equals?
134
What is the slope of the line y equals 7x plus 8 over 3?
7 and the y intercept is 8/3
What is the answer to 4x plus y equals 9 and 7x-8y equals 6?
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
4xy plus 1 equals 3y-7x solve for y?
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
What is the slope of 7x plus y equals 6?
7x + y = 6 y = 6 - 7x dy/dx = 0-7 = -7 Slope = -7
How do solve 7x plus y equals 8 in y equals mx plus b form?
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
If x equals 10 and y equals 8 then 7x plus 8y equals?
134
Solve for y 7x plus y equals 4?
7x + y = 4y = 4 - 7x
What is the slope of the line y equals 7x plus 8 over 3?
7 and the y intercept is 8/3
What is the standard form of y equals -7x plus 6?
7x+y=6
What is the solution to 7x plus y plus z equals 6 7x plus y plus 4z equals 9 y plus x equals 6?
7x + y + z = 6 7x + y + 4z = 9 y + x = 6 Take the first two statements and subtract them. 7x + y + z = 6 7x + y + 4z = 9 _____________ 0 + 0 - 3z = -3 Therefore: z = 1 Then you are left with: 7x + y + 1 = 6 7x + y + 4 = 9 which is impossible, so this is an impossible equation.
What is the y intercept of y equals 7x plus 10?
The Y intercept of y=7x+10 is 10.
What is the answer to 4x plus y equals 9 and 7x-8y equals 6?
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
What is the solution to 7x plus y plus 3 equals y?
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
What is the slope of this 7x plus y equals 6?
6
4xy plus 1 equals 3y-7x solve for y?
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
What is the slope of 7x plus y equals 6?
7x + y = 6 y = 6 - 7x dy/dx = 0-7 = -7 Slope = -7
