(49•x-36)+27=1000:25

Let's solve the equation step by step:

1. Start with the equation: \[ (49 \cdot x - 36) + 27 = 1000 \div 25 \]

2. Simplify the right side: \[ 1000 \div 25 = 40 \] So the equation becomes: \[ (49 \cdot x - 36) + 27 = 40 \]

3. Combine the constants on the left side: \[ 49 \cdot x - 36 + 27 = 40 \] This simplifies to: \[ 49 \cdot x - 9 = 40 \]

4. Add 9 to both sides: \[ 49 \cdot x = 40 + 9 \] Which simplifies to: \[ 49 \cdot x = 49 \]

5. Divide both sides by 49: \[ x = 49 \div 49 \] This simplifies to: \[ x = 1 \]

Thus, the solution to the equation is: \[ \boxed{1} \]
