Answer:
x = 2 and y = 1
Step-by-step explanation:
A) 5x+y=11
B) x - y = 1.
(Solving by substitution)
B) x - 1 = y
A) 5x + (x -1) = 11. 6x-1=11. 6x = 11+1
6x = 12
x = 12/2. x = 2
B. 2 - 1 = y. y = 1

Answer:
I'm pretty sure the answer to number one is 12g.
Step-by-step explanation:
To combine like terms, you combine all of the same variables.
For example, if you have 5x+7y+5x, you would combine like terms to make 10x+7x.
So for your first problem, we know that the combined like term is 15g. We know that one of the numbers combined was 3g. With that knowledge, you can subtract 15g-3g and get 12g.
I hope this makes sense, and helps you answer your other questions!
