or,2x-x=-4-3

x= -7

hope it will

Good luck on your assignment

x= -7

Step-by-step explanation:

To solve this equation, we want to find out what x is. We have to get x by itself.

Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.

2x+3=x-4

x is being added to -4. The opposite of addition is subtraction. Subtract x from both sides.

2x-x+3=x-x-4

2x-x+3= -4

x+3= -4

3 is being added to x. The opposite of addition is subtraction. Subtract 3 from both sides.

x+3-3= -4-3

x= -4-3

x=-7

Let's check our solution. Plug -7 in for x in the original equation.

2x+3=x-4

2(-7)+3= -7-4

-14+3= -7-4

-11= -11

Both sides are the same, so we know that -7 is the solution.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
