Answer:
x= 3/7 i.d.k if this is correct I did it in my brain
Multiply 2x by each term in the parentheses:
2x(x - 3)
2x^2 - 6x
Answer:
2x^2 - 6x
You mean -2x+5y=20 if it was that's how you do it
so if you're finding the x intercept the y will turn to 0 why because you're only looking for x their's no need for y
so it will be -2x+0=20
-2x=20 if it's multiplication then you change it to division
-2x/-2=20/-2
x=-10
