If the first equation is multiplied by 3 and then the equations are added, the result is _____. 3x + y = 3 x - 3y = -2 A:10x = 11 B:10x = 7 C:8x = 7
Chris, I need help myself, in understanding where you want your helpers to focus. You've typed in five equations. Are we to add them all together? What's your goal?
Its the choices actually
the last three are choices, sorry
I should have seen that myself. Sorry here too. This goes to show how important it is to be clear when you type in problem and possible answers; perhaps you could label the answers a, b, c, d.
the first equation is 3x + y = 3 multiply the equation by three, mean multiply both sides by three, like this 3*(3x + y) = 3*(3) simplify this
Following Unkle's suggestion, Type 9x + 3y = 9 followed by the 2nd equation: x - 3y = -2 ---------- Add these 2 equations together, column-by-column.
