Animal y=5.4x+34
person y=12x+8.5 y is weight x is years. when is the weight the same

Step-by-step explanation:

Animal                 Person

y = 5.4x + 34       y = 12x + 8.5; where y - weight, x - years

looking for when weight (y) is the same, so we need

animal weight (y) = person weight (y)

            5.4x + 34 = 12x + 8.5

          -5.4x           -5.4x

                      34 = 6.6x + 8.5

                   -8.5             -8.5

                   25.5  = 6.6x     divide both sides by 6.6

                         x = 3.86  years

not sure if you need your answer in decimal or what, but you can adjust accordingly.
