Given: q=7m+3n, r=11-2m, s=n+5,and t =-m-3n+8 simplify q-[r+s]-t

Simplify

The answer is:

Step-by-step explanation:

We have the expressions:

Now, we need simplify:

We need to replace each term by the expressions:

We need to remember the rule of signs:

With this in mind we solve the parentheses:

let's group common terms

We must add and subtract common terms:

The answer is:

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
