You cannot solve x plus y since that is an expression, not an equation (nor inequality).

By graphing the lines on the coordinated plane they will intersect at (2, -4) which is the solution of the equations

(x4 + y4)/(x + y) = Quotient = x3 - x2y + xy2 - y3 Remainder = - 2y4/(x+y) So, x3 - x2y + xy2 - y3 - 2y4/(x+y)

The solution consists of the infinite number of points on the line which is defined by y + x = 6.

2y4(16 - x4) = 2y4 (4 + x2)(4 - x2) = 2y4(4 + x2)(2 + x)(2 - x)

If you mean: y = 4x-2 and y = -x+3 then when plotted on the Cartesian plane the lines will intersect at (1, 2) because x = 1 and y = 2

There are several ways to solve x2-x-12. The easiest way, if you have a graphing calculator, is to put y = x2-x-12 and y = 0 into the graph and then solve for the intercepts. A way to do it without a graphing calculator is by factoring. x2-x-12 factors into (x-4) and (x+3). Then set (x-4) and (x+3) each equal to zero and solve. (x-4)=0 becomes x=4. (x+3)=0 becomes -3. Therefore, the answers are -3 and 4.

Graph the equation then find the x intercepts.

Its kind of hard to draw a graph in pure text... Try plugging your equation into www.wolframalpha.com/ ;)

How do you solve 4y plus x equals 8

There is not enough information to solve for x. x+5x+15 must equal something (is it 0?) in order to solve for x.

you can not solve this equation

The equation does not have a solution.

x=b-a

You cannot since it has no solution.

To solve for x, we'd have to know what this expression equals.

Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7

-50

x=9 squared

[x + y = 6] has an infinite number of solutions.

If you mean: 4x -3y = 1 and x -2y = 4 then the solutions are x = -2 and y = -3

x=4 x=0

To solve x + x + x + x, set the problem up as multiplication like this 4x = 128. Divide both sides of the problem by 4. You will get x = 32. To check your work, substitute 32 for the x and do the math. 4 x 32 = ?. If the answer is 128, the answer is correct.
