Question

Resolva as equacoes
A)2×-5=×+1
b)2×+3=×+4
C)4×-7=8×-2

Answer 1

Resposta:

A) x=6

B) x= 1

C) $x=-\frac{5}{4}$

Explicação passo-a-passo:

A ) 2X - 5=x+1

2x - x -5 =1

2x - x=1+5

x= 1+5

x+6

B) 2x-5=x+4

2x-x+3=4

2x-x=4-3

x=4-3

x=1

C ) 4x-7=8x-2

4x-8x-7=-2

4x-8x= -2 +7

-4x= -2+7

-4x=5

-4x=5

 $x=-\frac{5}{4}$
