Answer 1

@563blackghost
I'm not 100% sure how to do this or even if I did this correctly but I still gave it a shot.

Answer 2

2x+7=4x-7
4x-2x=7+7
2x=14
4x=2*2x=2*14=28

Answer 3

Not quite right. To solve you first analyze the triangle. It indicates two sides are equal so `Side AC equal to Side AB`. Lets set this up in an equation.

\(\LARGE\bf{AC=AB}\)

Substitute.

\(\LARGE\bf{2x+7=4x-7}\)

\(\LARGE\bf{-2x=-14}\)

\(\LARGE\bf{x=7}\)

You then input for side BC.

\(\huge\bf{BC=4(7)}\)

Answer 4
