Would be appreciated : ) how do you know which inverse operation to perform first when an equation contains two operations? which inverse operation do you perform first when solving the equation: 12 = 10 − 3x? which inverse operation do you perform last when solving the equation: 3/5x − 12 = 18?

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

associative property hopes this ! : )
