Question

Determine o valor de x
3 (-1) -4 (×-2) =0

Answer 1

Resposta:

x=5/4

Explicação passo-a-passo:

3(-1)-4(x-2)=0

3×(-1)-3(x-2)=0

3×(-1)

-(3×1)

-3

3×(-1)-4(x-2)=0

-3-4(x-2)=0

3×(-1)-4(x-2)=0

-4(x-2)

-4x-4x(-2)

-4x+8

3×(-4)-4(x-2)=0

-3-4x+8=0

-3+8

+(8-3)

5

-3-4x+8=0

5-4x=0

5-4x-5=0-5

-4x=0-5

5-4x-5=0-5

-4x=-5

5-4x=0

-4x=-5

-4x÷(-4)=-5÷(-4)

x=-5÷(-4)

-4x÷(-4)=-5÷(-4)

x=5÷4

-4x÷(-4)=5÷(-4)

x=5/4

-4x=-5

x=5/4

Resposta

x=5/4
