Answer:Let x = pay per hour as a carpenter and y = pay per hour as a blacksmith
Last week she worked 12 hours as a carpenter
earning 12x dollars
and 20 hours as a blacksmith
earning 20y dollars
and earned a total of $860
and those two things add up to 860.
Do the same with the other sentence, giving you a second equation.
Step-by-step explanation:
The answer is: [A]: "No solution" .
_______________________________________________
Note: Given:
_______________________________________________
y = 4x + 8 ;
y = 4x + 2 ;
_______________________________________________
Since: "y = y" ;
4x + 8 = 4x + 2 ; which is not true;
______________________________
4x + 8 ≠ 4x + 2 ; since, "8 ≠ 2" ;
Note: Suppose: "4x + 8 = 4x + 2" ;
→ Subtract "4x" from each side of the equation:
4x + 8 − 4x = 4x + 2 − 4x ;
to get:
_________________
" 8 = 2 " ; not true ; since "8 ≠ 2" ;
______________________________
Also, suppose:
_______________________________
4x + 8 = 4x + 2 ;
→ Subtract "2" from BOTH SIDES of the equation;
4x + 8 − 2 = 4x + 2 − 2 ;
to get:
4x + 6 = 4x
(Note: "4x + 0 = 4x" ; but "4x + 6 ≠ 4x") l
But even if we have:
4x + 6 = 4x ;
→ Subtract "4x" from EACH side of the equation:
4x + 6 − 4x = 4x − 4x ;
to get:
6 = 0 ; which is not true; "6 ≠ 0" .

The correct answer is: [A]: "No solution" .

For this case we have the following expression:
For power properties we have:
In the division, when we have the same base, the exponents are subtracted.
We then have to rewrite the expression:
Answer:
Completing the expression we have:
