Select the correct answer. A mistake was made in the steps shown to simplify the expression. Which step includes the mistake?
* + 3(4 – 1) – 7 + 23
Step 1: = 9 + 3(3) – 7 + 23
Step 2: * + 3(3) – 7 + 8
Step 3: = (3) – 7 +
Step 4: = 7+8
Step 5: = 1 + 8
Step 6: = 4 17
СА.
Step 4

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

i would you but i don't under stand the qustion

step-by-step explanation:

x=-2

step-by-step explanation:

i began by flipping the problem to give me x= on the left (keeps it clearer for me).   so my problem simply became 10x-3=4x-6.  

1)   subtract 4x from the right side, which equals 0.   you do the same to the left of the equal as the right; therefore, subtract 4x from 10x, leaving 6x on the left.

              10x-3=4x-6   :   4x-4x on the right leaves only the -6        

2)             6x-3= 0-6 :    

                6x+3=   -6

3) divide
