I have this equation: p/8 - 1 = 3
To solve, I know I have to get rid of the 8 by multiplying....my question is:
Do I multiply p/8, -1, AND 3 by 8, or just the p/8 to get rid of the 8, and then 3 x 8???
Assuming that you posted the equation correctly, add 1 to both sides, THEN multiply both sides by 8.
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
p/8 - 1 = 3
// move one over by adding
p/8 - 1 + 1 = 3 + 1
// result will be:
p/8 = 4
// cross multiply to move the 8 over
p/8 * 8 = 4 * 8
// result will be:
p = 32
