1836:(26-4•y)=102

To solve the equation \( 1836 = 26 - 4y \), we can follow these steps:

1. Isolate the term with \( y \): Subtract 26 from both sides of the equation: \[ 1836 - 26 = -4y \] This simplifies to: \[ 1810 = -4y \]

2. Solve for \( y \): Divide both sides by -4: \[ y = \frac{1810}{-4} \] This simplifies to: \[ y = -452.5 \]

Thus, the solution is \( y = -452.5 \).
