You multiply both equations by a factor to get them to have the same X coefficient, the first by 5 and the second by 2, you get 10x-15y=5 and 10x+8y=28. Then you subtract the equations to get 23y=23, y=1, plug y into first equaition, x=2. Answer is (2,1)
Hi reminder!!! just wanted to let you know that you are beautiful DONT pay attention to what other people say Ily :)
Y and x are the variables
Answer:
x=4
Step-by-step explanation:
We can modify the Pythagorean Theorem to fit our needs and solve x. We know our c and our a so to find x or b we use c^2-a^2=b^2. Lets input our knowns. 5^2-3^2=x^2. Lets start solving by squaring.
25-9=x^2
Subtract
16=x^2
Take the square root
4=x
