2x + 10 = 16
2 x plus 10 equals 16

2(x + 10) = 16
2 Left Parenthesis x plus 10 Right Parenthesis equals 16

10(x + 2) = 16
10 Left Parenthesis x plus 2 Right Parenthesis equals 16

2(x − 10) = 16

Answer 1

To identify the equation for which the order of steps is to first divide both sides by 2 and then to subtract 10 from both sides, we can analyze each option:

1. Equation: 2x + 10 = 16

   • If we divide both sides by 2, we get: \[ x + 5 = 8 \]
   • Subtracting 5 gives: \[ x = 3 \]
   • This matches the required order of steps.

2. Equation: 2(x + 10) = 16

   • Dividing both sides by 2: \[ x + 10 = 8 \]
   • Subtracting 10 gives: \[ x = -2 \]
   • This does not match the order.

3. Equation: 10(x + 2) = 16

   • Dividing both sides by 10: \[ x + 2 = 1.6 \]
   • Subtracting 2 gives: \[ x = -0.4 \]
   • This does not match the order.

4. Equation: 2(x − 10) = 16

   • Dividing both sides by 2: \[ x - 10 = 8 \]
   • Subtracting 10 gives: \[ x = 18 \]
   • This does not match the order.

Ultimately, the only equation where the order of steps is to first divide both sides by 2 and then subtract 10 is:

2x + 10 = 16.

−21

Answer 3

To solve the equation \(-4(z + 12) = 36\) for \(z\), follow these steps:

1. Divide both sides by -4: \[ z + 12 = \frac{36}{-4} \] \[ z + 12 = -9 \]

2. Subtract 12 from both sides: \[ z = -9 - 12 \] \[ z = -21 \]

Thus, the solution for \(z\) is −21.
