Answer 2

To solve each of these equations for their respective variables, let's go through them one by one:

1. X - 6 = 0 To solve for X, we need to isolate it on one side of the equation. Add 6 to both sides: X = 0 + 6 X = 6

2. -9 + x = -5 To solve for x, isolate it on one side of the equation. Add 9 to both sides: x = -5 + 9 x = 4

3. 7 - y = 21 To solve for y, isolate it on one side of the equation. Subtract 7 from both sides: -y = 21 - 7 -y = 14

Now, to get y alone, we need to multiply both sides by -1 (to keep the equation balanced): y = -14

4. (3/5) + z = (3/1/2) First, let's simplify the right side of the equation: (3/1/2) = (3/1) ÷ 2 = 3 ÷ 2 = 1.5 Now, to solve for z, isolate it on one side by subtracting (3/5) from both sides: z = 1.5 - (3/5) To subtract fractions, we need a common denominator, which is 5 in this case: z = (5/5) * 1.5 - (3/5) z = (7/5) z = 1.4

5. -5y = 5/9 To solve for y, isolate it by dividing both sides by -5: y = (5/9) ÷ (-5) y = -(1/9)

So, the solutions for the variables are: X = 6 x = 4 y = -14 z = 1.4 y = -(1/9)
