1. four times the sum of a number and 3 is 7 times the number decreased by 3. find the number

2. thirty decreased by 3 times a number is 6 less than 3 times the number. find the number

pls

Step-by-step explanation:

Question 1:

First, write the equation out:

4(x+3)=7x-3

solve for x:

4x+12=7x-3

15=3x

x=5

Question 2:

Do the same on the second question:

30-x=3x-6

36=4x

x=9

First you have to multiply 30 times 60 which is 1800 then you have to subtract 1800 by 80 which is 1720, then you will multiply 1720 by 2 which is 3440. Hope this helps(:
