Answer:
17 and 10
Step-by-step explanation:
Write the problem as an equation.
a+b=27
a=b-7
Where a and b are the two numbers you are trying to find. You could use any variables. Then solve.
b+(b-7)=27 Sub (b-7) for a
2b-7=27 Group like terms
2b=34 Add 7 to both sides
b=17 Divide both sides by 2.
Because b=17, a must be 10.
The answer is
In step 2, the addition property of equality was applied.
In step 4, the division property of equality was applied.
Proof that the answer is correct.
