Question

Responda A)4(x+10)-2(x-5)=0 B)(4X+6)-2X=(x-6)+10+14 C)5(x-3)-4(x+2)=2+3(1-2x)

Answer 1

a)
4(x + 10) - 2(x - 5) = 0 
4x + 40 - 2x + 10 = 0
2x + 50 = 0
2x = - 50
x = - 50/2
x = - 25
---------------------------------------------------------------
B)
(4x + 6) - 2x = (x - 6) + 10 + 14 
4x + 6 - 2x = x - 6 + 24
2x + 6 = x + 18
2x - x = 18 - 6
x = 12
----------------------------------------------------------
C)
5(x - 3) - 4(x + 2) = 2 + 3(1 - 2x)
5x - 15 - 4x - 8 = 2 + 3 - 6x
x - 23 = 5 - 6x
x + 6x = 5 + 23
7x = 28
x = 28/7
x = 4
