Question

Help would be appreciated :)

Answer 1

PEMDAS

When solving an equation we do them in reverse order

AS  adding and subtracting

MD  multiplication and division

E exponents

Basically we are trying to get the variable alone.

12=10-3x

subtract 10 from each side

then divide by -3 on each side

3/5 x -12 = 18

first add 12 to each side

then multiply by 5/3 to each side
