Answer 1

Question 1:

For this case we must rewrite the following equation:

$-3x + y = 5$

If we add 3x to both sides of the equation we have:

$y = 5 + 3x$

Thus, we have that an equivalent expression is option C.

Answer:

Option C

$y = 5 + 3x$

Question 2:

For this case we must solve the following equation:

$-5x + 5 = -40$

Subtracting 5 from both sides of the equation we have:

$-5x = -40-5\\-5x = -45$

Dividing between -5 on both sides of the equation we have:

$x = \frac {-45} {- 5}\\x = 9$

Answer:

Option B
