Solve.

2, left parenthesis, 2, z, plus, 10, right parenthesis, equals, 36
2(2z+10)=
36

1 answer

To solve the equation \( 2(2z + 10) = 36 \), follow these steps:

  1. Distribute \( 2 \) on the left side: \[ 4z + 20 = 36 \]

  2. Subtract \( 20 \) from both sides: \[ 4z = 36 - 20 \] \[ 4z = 16 \]

  3. Divide both sides by \( 4 \): \[ z = \frac{16}{4} \] \[ z = 4 \]

So, the solution is \( z = 4 \).
