Translate into an equation:

1. Five times the sum of twice a number, \( x \), and six is thirty.

Equation: \[ 5(2x + 6) = 30 \]

Find the number: \( x = \)

2. The difference between a number, \( x \), and eleven is three.

Equation: \[ x - 11 = 3 \]

Find the number: \( x = \)

Solve and check:

3. \[ 4y - 3 = 12 + 3(y - 2) \]

Solve for \( y \): \( y = \)

4. \[ 10x - 2(4x - 7) = 28 \]

Solve for \( x \): \( x = \)
