Question

(4x )- (20) +(×)+(6×)=90​

Answer 1

Respuesta:

El valor de x es 10

Explicación paso a paso:

• (4x) - (20) + (x) + (6x) = 90
• 4x - 20 + x + 6x = 90
• 11x - 20 = 90
• 11x = 90 +20
• 11x = 110
• x=110/11
• x = 10

Comprobación:

• (4(10)) - (20) + (10) + (6(10)) = 90
• 40 - 20 + 10 + (6(10)) = 90
• 40 - 20 + 10 + 60 = 90
• 110 - 20 = 90
• 90 = 90

Answer 2

$(4x) - (2 0) + (x) + (6x) = 90 \\ 4x - 20 + x + 6x = 90 \\ 11x - 20 = 90 \\ 11x = 90 + 20 \\ 11x = 110 \\ x = 110 | : 11 \\ \bf \: x = 10$
