Ответ:
- \((2x+5)\cdot3=15\) → \(2x+5=5\) → \(2x=0\) → \(x=0\).
- \((8+4x)\cdot2=48\) → \(8+4x=24\) → \(4x=16\) → \(x=4\).
- \((11-3x)\cdot3=15\) → \(11-3x=5\) → \(-3x=-6\) → \(x=2\).
- \((5x+2)\cdot5=60\) → \(5x+2=12\) → \(5x=10\) → \(x=2\).
- \((49-11x):3=9\) → \(49-11x=27\) → \(-11x=-22\) → \(x=2\).
