A biologist is comparing the growth of a population of flies per week to the number of flies a lizard will consume per week. She has devised an equation to solve for which day (x) the lizard would be able to eat the entire population. The equation is 3x = 5x − 1.

Explain to the biologist how she can solve this on a graph using a system of equations.

@Preetha @Vocaloid @volleyballlover55 Please help!

vocaloid · Answer

since we want the x value where both sides of the equation are equal, we can split the equation

3x = 5x − 1.

into

y = 3x and
y = 5x - 1

we can then graph these and solve for x

it doesn't actually ask for the answer, it just wants you to explain how to set it up, which i just did
