Мишата · Answer 1

4 (x+3) = 5 (x-2)

4x + 12 = 5x - 10

x = 22

-2 (x-5) + 3 (x-4) = 4x+1

-2x + 10 + 3x - 12 = 4x + 1

3x = - 3

x = - 1

3 (x-1) = 2 (x+2)

3x - 3 = 2x + 4

x = 7

3 (x-5) - 2 (x+4) = - 5x+1

3x - 15 - 2x - 8 = - 5x + 1

6x = 24

x = 4

4 х+12=5 х-10

4 х-5 х=-10-12

-х=-22

х=22

-2 х+10+3 х-12=4 х+1

-2x + 10 + 3x - 12 = 4x + 1

3x = - 3

x = - 1

3 (x-1) = 2 (x+2)

3x - 3 = 2x + 4

x = 7

3 (x-5) - 2 (x+4) = - 5x+1

3x - 15 - 2x - 8 = - 5x + 1

6x = 24

x = 4

4 (x+3) = 5 (x-2)-2 (x-5) + 3 (x-4) = 4x+13 (x-1) = 2 (x+2)3 (x-5) - 2 (x+4) = - 5x+1

4 (x+3) = 5 (x-2)

-2 (x-5) + 3 (x-4) = 4x+1

3 (x-1) = 2 (x+2)

3 (x-5) - 2 (x+4) = - 5x+1
