Add 5 to both sides 5x + 12 = 3x Subtract 3x from both sides 2x + 12 = 0 Subtract 12 from both sides 2x = -12 Divide both sides by two x = -6 Lather, rinse, repeat on the next problem.

Brackets first (5+20/2*5) Then division is first. 20/2 =10 10*5 =50 5+50=55 2*55 =110 10+110=120 Now on the other side of the minus sign. There is both multiplication and division. Since you did division first on the left, do division first. 2/2 =1 2*1*2 =4 Therefore 120-4 = 116

The correct answer is 116 but you need to use the proper algebraic priorities. Think of this acronym to help you remember: BIDMAS Brackets Indeces Division & Multiplication Addition & Subtraction Remember addition and subtraction last. So let's look at 2^(5+20/2^5) right the brackets are evaluated first but within the brackets we have a multiplication and division, so we do the multiplication first 2*5 = 10 20/2 = 10 10*5 = 50 (if you wanted to do 20/10 you needed to have the 2*5 bit in brackets otherwise teh 20 is divided by 2 and then the result multiplied by 5 as division and multiplication are on the same priority) 5+50 = 55 2*55 = 110 10+ 110 = 120 now for the subtraction 2*2 =4 4/2 = 2 2*2 =4 Therefore our whole expression simplifies to 120-4 = 116 Hope this helps.

First: combine "like" terms - subtract 3x from both sides (when you move a term to the opposite side, always use the opposite sign). 5x -3x + 7 = 3x -3x - 5 5x -3x + 7 = - 5 2x + 7 = - 5 SEc: subtract 7 from both sides... 2x + 7 - 7 = - 5 - 7 2x = - 5 - 7 2x = - 12 Third: solve "x" by isolating it - divide each term by 2. 2x/2 = - 12/2 x = -12/2 x = - 6

F = multiply the first number in each set of parenthesis O = multiply the outside number in each set of parenthesis I = multiply the Inside number in each set of parenthesis L = multiply the last number in each set of parenthesis Then all you have to do is clean it up and combine like-terms. F ---> 5b x 5b = 25b squared O ---> 5b x -3g = -15bg I ---> 3g x 5b = 15bg L ---> 3g x -3g = -9g squared ANSWER -------> 25bsquared - 9g squared I really hope this helps you out. This is probably the best I can explain it.
