Y=2x y=-1/2x+5 system of equations
dalvyx [7]

Answer:

<em><u>x=2, y=4</u></em> (as a point,) (2, 4)         (last part is unnecessary unless you are graphing)

Step-by-step explanation:

Use substitution.

Substitute y for 2x.

Since y=2x, you can plug 2x into the place where y goes...

Instead of y=-1/2x+5

2x=-1/2x+5....Now solve

2.5x=5 (Sorry my computer cannot type fractions very clearly)

/2.5    /2.5        (dividing by 2.5 on both sides)

<u><em>x=2</em></u>

Now just plug x into any of the equations to find y (preferably the easier one).

y=2x becomes

y=2*(2)

=4

<em><u>y=4</u></em>

Help asap idek what to do
daser333 [38]

So to solve this question, your goal is to find out how the way it is solved is not correct.

Your answer would be: On the third line, the student adds the 8 to both sides instead of subtracting. The way the initial equation is given is

y-(-8)=-6(x-2). After distributing the six, the student should make the 8 positive because subtracting a negative makes a positive. After solving, the equation should look like: y(+8)=-6x+12, so you would subtract the 8 from both sides instead of adding it, and solve from there.
