Can you me with this?
14 + 5(x + 3) - 7x

Well first you have to do distributive property with the parenthesis, multiply 5 times x and 5 times 3 to get 5x and 15 now you have 14+5x+15-7x, now add common like terms(these are terms taht have the same number variable or both) so your common numbers will be 14 and 15, and 5x and -7x now add or subtract them to get -2x+29 now you have to set x by itself so set this binomial equal to 0 to get -2x+29=0 subtract the 29 from both sides and get -2x=-29 now divide 2 by both sides to get x=29/2

Hope this helps

You multiply 5,x,3 and y will get 5x+15.Then you add 7x and 5x  and you get 12x. Finally you subtracted 15&14 and get 1 then you divide 12x from 1 and get 12.

Ithink it's the first one ( let me know if it right)

The answer is 1532.75
