Question

The equation the quantity 3x minus 15 divided by 2 equals 4x models temperature change, where x represents the difference in degrees in the last 24 hours. Solve for x.

x = 11
x = 6
x = −3
x = −15

Answer 1

translate the equation into mathematical terms

(3x-15)/2 = 4x

we solve:

4x*2 = 3x-15

8x=3x-15

8x-3x = -15

5x=-15

x=-3
