Plot the straight line representing 2y = 12 - x.
Plot the straight line representing 3y = x - 2
The coordinates of the point of intersection of these two lines is the solution to the simultaneous equations.
The given equation y=3+x is a linear line with the slope of 1 and y-intercept of 3.
I think it is 3.14 that equals to pi when u solve it

A parabola is a graph of a 2nd degree polynomial function. Two graph a parabola, you must factor the polynomial equation and solve for the roots and the vertex. If factoring doesn't work, use the quadratic equation.
It depends on which variable you wish to solve for.
You plot the equation as a graph. Every one of the infinitely many points on the graph is a solution.
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
This equation is not possible unless you are given another equation related to x and y. Then you could use simultaneous equations to solve this. However in this came this question is impossible
Its kind of hard to draw a graph in pure text... Try plugging your equation into www.wolframalpha.com/ ;)
The elimination method only works with simultaneous equations, hence another equation is needed here for it to be solvable.

Solve the equation for y. This will give you an equation similar to y = ax + b, where a is the slope, and b is the y-intercept.
x = 5 and y = -8 Solved by forming a simultaneous equation and eliminating y in order to find the values of x and y.
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
You'll need another equation to solve this one. The equation you give has a graph that is a line. Every point on the line is a solution to the equation so there are infinitely many solutions.
The solutions work out as: x = 52/11, y = 101/11 and x = -2, y = -11
