Answer:
Step-by-step explanation:
x + 13 + 4x + 2 = 180
Add the like terms,
5x + 15 = 180
Subtract 15 form both sides
5x + 15 - 15 = 180 -15
5x = 165
Divide both sides by 5
5x/5 = 16/5
x = 33

−3 ( −3b + 5 ) + 9 ( 7b + 5
= 6(12b+5)
The two numbers are 3 and 18, if the sum of two number is 21 and the second number is six times the first number.
Step-by-step explanation:
The given is,
The sum of two numbers is 21
The second number is six times the first number
Step:1
Let, m - First number
n - Second number
Step:2
From given,
n - 6m ( The second number is six times the first number )
Equation becomes,
Sum = m + n
Where,
21 = m + ( 6m )
21 = 7m
m = 3
Substitute m value n becomes,
n = 6m
= (6 × 3)
n = 18
Result:
The two numbers are 3 and 18, if the sum of two number is 21 and the second number is six times the first number.
