Question

ayudemen xfavor la necesito doy coronitas​

Answer 1

Explicación paso a paso:

A) 5x= 8x-15

5x -8x = 15

-3x = 15

x = 15:(-3)

x = -5

B) 5x +6 = 10x +5

5x -10x=5-6

-5x = -1

x = -1/ (-5)

x = 1/5

C) 21-6x = 27 -8x

-6x +8x = 27 -21

2x = 6

x = 6:2

x= 3

Answer 2

Explicación paso a paso:

• A) 5x = 8x - 15
• 5x - 8x = - 15
• -3x = -15
• x = -15/-3
• x = 15/3
• x = 5

• B) 5x + 6 = 10x + 5
• 5x - 10x + 6 = 5
• 5x - 10x = 5 - 6
• -5x = - 1
• x = -1/-5
• x = 1/5

• C) 21 - 6x = 27 - 8x
• 21 - 6x + 8x = 27
• 8x - 6x = 27 - 21
• 2x = 6
• x = 6/2
• x = 3
