$y = 5 - 3x$

Put this value of $y$ in first equation : $6x + 4(5-3x) = 17$

anonymous · Answer

Distribute 4 to brackets and add like terms, try to find $x$..

You can also take advantage of your solutions and plug them in and check which one is right.

But water is right, his is a good way to learn where plugging in solutions more of if you're in a hurry :P
