Question 1:
For this case we must rewrite the following equation:
[tex]-3x + y = 5[/tex]
If we add 3x to both sides of the equation we have:
[tex]y = 5 + 3x[/tex]
Thus, we have that an equivalent expression is option C.
Answer:
Option C
[tex]y = 5 + 3x[/tex]
Question 2:
For this case we must solve the following equation:
[tex]-5x + 5 = -40[/tex]
Subtracting 5 from both sides of the equation we have:
[tex]-5x = -40-5\\-5x = -45[/tex]
Dividing between -5 on both sides of the equation we have:
[tex]x = \frac {-45} {- 5}\\x = 9[/tex]
Answer:
Option B
