So here we just are gonna distribute and simplify.
You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that
expand, collect like terms, factor to find x, then plug x value back into original equation to find y
286. you just subtract the two numbers
1.35=area
formula for area of a triangle is base times height divided by two and therefore 1.5 times 1.8 divided by two is 1.35
