Your answer should be 2x+5 if you are supposed to simply the expression
Estimate too large
estimate first
the estimate is too large.
bring down the next digit.
(x,y) = (r,16)
With this knowledge, plug in r for x, and 16 for y
16 = 2(r) - 4
Isolate the r, add 4 to both sides
16 (+4) = 2r - 4 (+4)
20 = 2r
Divide 2 from both sides
20/2 = 2r/2
r = 20/2
r = 10
hope this helps
