I'm having trouble solving this I don't know the steps what is 21x+6+90=180
I don't know if its that problem exactly but I need an answer and an explanation

x=4

Step-by-step explanation:

No answer needed.

x=4

Step-by-step explanation:

21x+6+90=180

First, we need to subtract the numbers.

21x=180-90-6

21x=84

Now, we need to find the value for 1x, so divide the whole equation by 21

84/21

21/21

x=4

Hope this helps!

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
