Q:
# Solve for x in the mathematical formula y = mx + b. Find the variables to complete the formula.x = _____ - _____ / _____

Accepted Solution

A:

y = mx + b. Solve for x:

Subtr. b from both sides. Then, y - b = mx

Next, divide both sides by m, to isolate x:

mx y-b

x = ----- = ------- (answer)

m m

Important:

"x = _____ - _____ / _____ "

is a bit ambiguous. Please enclose the numerator inside parentheses, like this:

x = ( _____ - _____ ) / _____ Then it becomes clear that we must perform

the subtraction first, before the division.

Subtr. b from both sides. Then, y - b = mx

Next, divide both sides by m, to isolate x:

mx y-b

x = ----- = ------- (answer)

m m
