Step-by-step explanation:
well you know that the square is 90 degrees so you set it up as 90=21x+6. Then you subtract 6 from both sides and it gets you 84=21x. Then divide 21 on both sides. So the answer is x=4
Y= x-3 2y-2x=-6
1) add the 2x to both sides// 2y=2x-6
2) divide the 2 on both sides// y=x-3
