4(x-1)=(x+14)-5(x+2)


3x-(x-8)=(X+12)


7x-5x+1=8-x-4


3x-4=-(x-8)


6x-3=3(x+4)


2(3x-5)=18-2-3-5


4x-3-6x=5+x-8

AYUDENME POR FAVOR

Respuesta:

4(x - 1) = (x + 14) - 5(x + 2) \\ 4x - 4 = x + 14 - 5x - 10 \\ 4x - 4 =  - 4x + 4 \\ 4x + 4x = 4 + 4 \\ 8x = 8 \\ x = 8 \div 8 \\ x = 1

Explicación paso a paso:

3x - (x - 8) =( x + 12) \\ 3x - x + 8 = x + 12 \\ 2x - x = 12 - 8 \\ 1x = 4 \\ x = 4

7x - 5x + 1 = 8 - x - 4 \\ 2x + 1 = 4 - x \\ 2x + x = 4 - 1 \\ 3x = 3 \\ x = 3 \div 3 \\ x = 1

3x - 4 =  - (x - 8) \\ 3x - 4 =  - x + 8 \\ 3x + x = 8 + 4 \\ 4x = 12 \\ x = 12 \div 4 \\ x = 3

6x - 3 = 3(x + 4) \\ 6x - 3 = 3x + 12 \\ 6x - 3x = 12 + 3 \\ 3x = 15 \\ x = 15 \div 3 \\ x = 5

2(3x - 5) = 18 - 2 - 3 - 5 \\ 6x - 10 = 18 - 10 \\ 6x  - 10 = 8 \\ 6x = 8 + 10 \\ 6x = 18 \\ x = 18 \div 6 \\ x = 3

4x - 3 - 6x = 5 + x - 8 \\  - 3 - 2x = x - 3 \\  - 2x - x =  - 3 + 3 \\   - 3x =  0 \\ x = 0 \div  - 3 \\ x = 0
