Solve equation 3x=2x+5

x=5

Step-by-step explanation:

So first you would subtract 2x from both sides to get:

1x = 5

Then you divide both sides by 1:

x = 5

3x = 2x + 5 —put X on one side so I

-2x = -2x + 5 —subtract 2x From both sides

X= 5 — the negative and positive cross out Leaves the 5 only on the right side on the left 3-2 is 1 so x is by itself.

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

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
