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 $x=\frac{y-8}{1.5}$
