Answer 1

Ответ: x = 3, c = -2, y = 1

Пошаговое объяснение:

1) 4 - x - 2x + 6 = 1;

3x = 9

x = 3;

2) 2c+2,5 -c = 0,5

c = -2

3) 99y+y = 100

100y = 100

y = 1

Answer 2

1. 4x - 2x + 6 = 1 Simplifying the left side: 2x + 6 = 1 Now, isolate the variable x by moving 6 to the right side: 2x = 1 - 6 2x = -5 Finally, divide both sides by 2 to find x: x = -5 / 2 x = -2.5

2. 2c + 2.5 - c = 0.5 Combining like terms on the left side: 2c - c + 2.5 = 0.5 c + 2.5 = 0.5 Now, isolate the variable c by moving 2.5 to the right side: c = 0.5 - 2.5 c = -2

3. y + 99y = 99 + 1 Combining like terms on the left side: 1y + 99y = 100y Now, combine the constants on the right side: 100y = 100 Finally, divide both sides by 100 to find y: y = 100 / 100 y = 1

The solutions are: x = -2.5 c = -2 y = 1
