Question

Determine o valor de x
A) 2(x-3)-(4x+3)=-10x+8

B) 5x-3x+10=2(-3x+8)

C)4x+x-1=2x+1
3 6 2

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

Answer 1

Explicação passo-a-passo:

A) 2(x-3)-(4x+3)=-10x+8

2x-6-4x-3=-10x+8

2x-4x+10x=6+3+8

8x=17

x=17/8

B) 5x-3x+10=2(-3x+8)

5x-3x+10=-6x+16

5x-3x+6x=16-10

8x=6

x=6/8

x=3/4

C) 4x+x-1=2x+1

4x+x-2x=1+1

3x=2

x=2/3

D) 4(x-3)-x =2x-1

4x-12-x =2x-1

3x-12=2x-1

3x-2x=-1+12

x=11
