You didnt give us the numbers but it should be 4 and -4
Answer:
ok so x is her currect age y is her age in 20 years
2x+6=y
x+20=y
that means that both sides are equal
2x+6=x+20
-6
2x=x+14
-x
x=14
so her currect age is 14 and lets plug in
14+20=34
her currect age is 14 and her age in 20 years is 34
Hope This Helps!!!
-.5 + 2, you can think of this as 2 - .5 as well, it would equal out to be 1.5.
