Answer 3

It looks like you've provided three equations. Did you want to solve for the variables x, y, and z in each equation? If so, I can help you with that.

Let's solve each equation step by step:

1. $49 - 3x = 108$ Subtract 49 from both sides: $-3x = 108 - 49$ $-3x = 59$ Divide by -3: $x = -\frac{59}{3}$ $x = -\frac{59}{3}$ or approximately $x = -19.67$

2. $9y - 89 = 55$ Add 89 to both sides: $9y = 55 + 89$ $9y = 144$ Divide by 9: $y = \frac{144}{9}$ $y = 16$

3. $74 - 8z = 2$ Subtract 74 from both sides: $-8z = 2 - 74$ $-8z = -72$ Divide by -8: $z = \frac{-72}{-8}$ $z = 9$

So, the solutions for the variables are: $x = -\frac{59}{3}$ or approximately $x = -19.67$ $y = 16$ $z = 9$
