Question

solve 3(x+4)-4(x+3)=7x+16
1: x=3
2: x=2
3: x=-2

Answer 1

distribute through all of the parenthesis

Answer 2

man ive been on this question for like 15 min i dont it

Answer 3

dont get it*

Answer 4

3(x + 4) - 4(x + 3) = 7x + 16
3x + 12 - 4x - 12 = 7x + 16
are you with me so far ?

Answer 5

yes

Answer 6

now we will combine like terms
-x = 7x + 16
still with me ?

Answer 7

kpajon are you writing a love letter?

Answer 8

oh yeah

Answer 9

.......

Answer 10

In this situation you have to input the three solutions.
1. 3(3+4)-4(3+3)=7(3)+16
3(7)-4(6)=21+16
21-24=37
-3 does not equal 37, therefore it is not a solution.
2. 3(2+4)-4(2+3)=7(2)+16
3(6)-4(5)=14+16
18-20=30
-2 does not equal 30, therefore it is not a solution.
3. 3(-2+4)-4(-2+3)=7(-2)+16
3(2)-4(1)=-14+16
6-4=2
2 does equal 2, therefore -2 is the solution.

Answer 11

lol you better love me after I did all that work -.-

Answer 12

-x = 7x + 16
subtract 7x from both sides
-x - 7x = 16
-8x = 16
x = -16/8
x = -2

check...
3(x + 4) - 4(x + 3) = 7x + 16
3(-2 + 4) - 4(-2 + 3) = 7(-2) + 16
3(2) - 4(1) = -14 + 16
6 - 4 = -14 + 16
2 = 2 (correct)

any questions ?

Answer 13

ty for the ANSWER!

Answer 14

lol -2 or 2

Answer 15

-2

Answer 16

oh nvm

Answer 17

The solution is -2

Answer 18

you do not need to plug in all solutions to find the answer....just solve for x.
