Okay so you would line them up then you would multiple 5 and 0 then 7 and 5 and then you add a 0 then you would get the answer 350 then you would multiply the same numbers then the answer you would get is 3500 then you add 3500+350=3850
Kyle is asked to solve a system of equations by substitution: 2x + 3y = 12 x - 2y = 4 which step should kyle take first? why?
2 answers:
The given system of equations is
and
From the given set of options, it would be best for Kyle if he takes <u>option C</u> as the first step. That is, "Kyle should solve the second equation for x because x has a coefficient of 1".
This is because it will make further solution easy. Let us know how.
The coefficient of x is 1. Thus, x will be represented as: after adding
to both sides. Now, this can be substituted in the first equation and we can solve for y. Once that is done we can easily solve for x using any of the two equations (whichever is the easiest).
