this week in math 10 we worked on systems. there arre 3 ways to find the answer. the first way is graphically solving the equation, this requires a graph, the first thing you do is change the form to y intercept then you graph the points using the slope and the starting point. the next way is substitution, to do this one you isolate the variable (x or y) then so you end up with x or y = then you substitute the x or y for the equation that comes after the x or y= then simplify for 0 pairs. the last way is elimination for elimination the first thing you do is you find the common factor then you add or subtract the equations then you simplify for 0 pairs.
