Answer:
-11
Step-by-step explanation:
-3w - 7 = 2
-3w (- 7 + 7) = 2 + 7
-3w = 9
-3w/-3 = 9/-3
w = -3
4w + 1
4(-3) + 1
-12 + 1
-11
Answer:
4w + 1 = -11
Step-by-step explanation:
Solving -3w - 7 = 2
By adding 7 to both sides of the equation we get -3w = 9
to get to w = ... we need to divide both sides with -3, which gives us
w = -3. You can check this answer by putting it back into the original equation ( -3 * -3 - 7 does equal 2, which means our solution for w is correct.
Now all we have to do is put our solution for w into the remaining equation:
4 * -3 + 1 = -12 + 1 = -11
