Question

what is the point intersection of 2x-y=3 and x +y =3

Answer 1

IF the sum of a number and 4 is multiplied by 2 the result is 28. what is the number? could you do that too?

Answer 2

Do you remember how to graph an equation in a basic way by folowing the y=mx+b method?
like, if you graph 2x-y=3
-y = 3-2x
y = -3 + 2x
y = 2x - 3


You do the same with x+y=3, and you'll get y = -x + 3

Answer 3

Now, combine the graphs and see where they intersect. The intersection point is the answer :)
