Answer:
(-6,-2)
Step-by-step explanation:
if you substitute y=-1/3x-4 into the first equation and simplify you get x=-6. then you substitute -6 into y=-1/3x-4 and get y=-2
I'm assuming you're trying to simplify the expression?
If so, start by combining like terms.
4x+56-57
becomes 4x-1
That is the furthest you can simplify. If it had an equals sign, it would be an equation, and you would solve for x algebraically. But, since there is no equals sign, it is just an expression, and you simplify it to the best of your ability.

Answer:
10 > v (if you don't trust me, check it yourself. Subsitute v for 10 in the first equation.
Step-by-step explanation:
1) 7 > v - 3
2) add 3 to both sides
3) so 7 plus 3 equals 10
So you basically do this
7 > v - 3 (ad 3 to both sides)
You get 10 > v (which is as simplified as possible)
Hope this helps! :)
