Question

ResolvA as equações?
a) 2× + 4 = x + 25
b)3 + 2y + y = 1
c)4× + 2× -5 = 10 -2×
d)4y + 20 = y + 31
e)5x + x + 2× + -20 = 50 -x

Answer 1

a) 2x-x+4-25=0
     x-21=0
     x=21

b) 3y+2=0
    3y=-2
     y=2/3

c) 8x - 13 = 0
    8x=13
    x=13/8

d) 3y= 11
    y=11/3

e) 7x= 70
    x=70/7
    x=10
