I am stuck on 2 questions and I would appreciate it if any of you guys could help me. thank you
1) y= 3(x²+3)
14x+y=1
2) x+5y=30
x²+ 4÷5x = y
1) Substitute the value of y into the second equation:
Then substitute these values of x back into the second equation to solve for y.
2) Sub y into the first equation:
Then substitute these values of x back into the first equation to find the corresponding values of y.
