#22. as you can see i tried to work it out, but to no avail.

If you make x the subject for the first equation
x + 2 = -2y
x = -2y - 2

Use that equation to substitute for x in equation 2

so the answer will be A

3x+9+4x+x=8x+9that's the answer for your question.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
