he weight of a chimpanzee, y, in pounds, x months after birth is modeled by the equation y=1.5x+8. Which represents the equation
soldi70 [24.7K]

The equation that represents x when solved is x=\frac{y-8}{1.5}

Given the equation that expresses the weight of a chimpanzee with respect to the months of birth as:

y = 1.5x + 8

We are to express x in terms of "y"

y = 1.5x + 8

Subtract 8 from both sides

y -8= 1.5x + 8-8\\y-8 = 1.5x\\Swap\\1.5x = y - 8

Divide both sides by 1.5

\frac{1.x}{1.5}= \frac{y-8}{1.5} \\x=\frac{y-8}{1.5} \\

Hence the equation that represents x when solved is x=\frac{y-8}{1.5}
