What is the value of y in the system of equations shown below?

7x − 7y = 49
3x − 16y = 34

Write as a product of 2 binomials and a monomial (factor out as much as possible from each binomial). ! i do not understand, any is appreciated : ) whoever gets the best answer recieves brainliest and points! (4x–12x²)(16y³+12y²)

Which of the fallowing best completes the sequence 5,10,15, a) 30 b) 22 c)25 d)35

Look at arnold's attempt to solve the equation for b: 3b = 12 b = 3 · 12 b = 36 describe the mistake that arnold made.
