How do you solve #3( y + 4) = 4( y - 6)#?
Solving for the y-variable gives us
So to solve the multistep equation, we need to use distributive property which gives us:
But let double check to ensure that this work on both sides.
So since both side of the equal sign is 120, we can say for sure that
first use the distributive property:
add 24 to both sides:
subtract 3y from both sides.
Follow the PEMDAS rules: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. You solve the equation using those steps in that order.
First, you distribute the three and the four as they're multiplying to the parentheses. You can't do anything more within the parentheses, so then you multiply like so-
Then you subtract
And finally, to isolate the variable and achieve your answer, you add
