Question

Resolva as equações:

A) 4x. + 25= 2(4x + 150)+ x
B) 10y - 30 + y= 2y + 240

Me ajudem pfvrr!!

Answer 1

A) 4x + 25 = 2(4x + 150) + x

4x + 25 = 8x + 300 + x

4x + 8x - x = 300 - 25

11x = 275

x = 25

B) 10y - 30 + y = 2y + 240

10y + y - 2y = +30 + 240

9y = 270

y = 30

Answer 2

A) 4x + 25 = 2 × (4x + 150) + x

4x + 25 = 8x + 300 + x

4x + 25 = 9x + 300

4x - 9x = 300 - 25

-5x = 275 ×(-1)

5x = -275

x = -275/5

x = -55

B) 10y - 30 + y = 2y + 240

11y - 30 = 2y + 240

11y - 2y = 240 + 30

9y = 270

y = 270/9

y = 30
