z=pq
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
why will the equations x+14=37 and x-14=37 have different solutions for x
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28
It is not possible to solve one equation in two unknowns (x and y). Two independent equations are required.
Its kind of hard to draw a graph in pure text... Try plugging your equation into www.wolframalpha.com/ ;)
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
k equals 5.6

Solve the following equation for A : 2A/3 = 8 + 4A
3x + 2y = 62x + 3y = -1You can use substition, elimation, or graphing to solve this system, but I prefer to use matrices. They are difficult to type out, but the answer is x = 4 and y = -3.
