Answer:
The numbers are 20 and 9
Step-by-step explanation:
Let the first number be x
Let the second number be y
For the first equation
One number is 7 less than 3 times the second number is written as
x = 3y - 7
For the second equation
The sum of the two numbers is 29
So we have
x + y = 29
Substitute the first equation into the second one
That's
3y - 7 + y = 29
4y = 29 + 7
4y = 36
Divide both sides by 4
y = 9
Substitute y = 9 into x = 3y - 7
That's
x = 3(9) - 7
x = 27 - 7
x = 20
The numbers are 20 and 9
Hope this helps you
