Solve the system of equations y=8x+15 and y=x+57

x=6, y=63

Step-by-step explanation:

since both equal y, they equal each other-

8x+15=x+57

7x=42

x=6

then to solve for y-

y=(6)+57

y=63

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

pls mark as brainliest

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
