Assuming we want to factor the formula to (x+3)(x+3), you want to have a +9 where there is a -4 now. So you must add 13.
Answer:
x = 63
Step-by-step explanation:
<u>Step 1: Solve for x by multiplying both sides by 9</u>
x/9 * 9 = 7 * 9
<em>x = 63</em>

Answer: x = 63
Line r is twice line m. i.e. r = 2s which means that they are linearly dependent.
Therefore there are infinitely many solution to the given set of equations.
Well first you would subtract 9 from both sides to isolate your variable
so it would look like
1/4y =-81/2
now you divide 1/4 from both sides
so you're left with
y = -34
