Zoe is solving the equation 3x-4=-10 for x solving for x

x = - 2

Step-by-step explanation:

Solve for x:

3 x - 4 = - 10

Add 4 to both sides:

3 x + (4 - 4) = 4 - 10

4 - 4 = 0:

3 x = 4 - 10

4 - 10 = - 6:

3 x = - 6

Divide both sides of 3 x = - 6 by 3:

(3 x) / 3 = (-6) / 3

3/3 = 1:

x = (-6) / 3

The gcd of - 6 and 3 is 3, so (-6) / 3 = (3 (-2)) / (3*1) = 3/3*-2 = - 2:

Answer: x = - 2
