Question

x+y=7 can someone help me I will medal

Answer 1

What are you trying to do? Solve for x or y?

Answer 2

x

Answer 3

Alright, you need to get x by itself on the left side. What is the first step do you think?

Answer 4

add x to both sides

Answer 5

No. You want x to stay on the left side, but y is there too. How do we get y on the right side?

Answer 6

add 7 to both

Answer 7

No, that will bring the seven onto the left side. You want the seven AND the y to be on the right side, what could you do to make 'y' go on the right side of the equals sign?

Answer 8

idk how

Answer 9

Subtract y from both sides. This is algebra.

x + y = 7
-y -y
x = y -7
Does that make sense?

Answer 10
