Question

a) 2x+4/11=0 b) 3/5x-3/10=0 c)8x-1=0 d) 3x-2/7=0 e) 11x-4=52,1 f)2(x-1)=4/3

Answer 1

a) 2x + 4/11 = 0
a) 2x = 0 - 4/11
a) 2x = -4/11
a) x = -4/11 : 2
a) x = -4/11 * 1/2
a) x = -2/11

b) 3/5x - 3/10 = 0
b) 3/5x = 0 + 3/10
b) 3/5x = 3/10
b) x = 3/10 : 3/5
b) x = 1/2

c) 8x - 1 = 0
c) 8x = 1
c) x = 1/8

d) 3x - 2/7 = 0
d) 3x = 0 + 2/7
d) 3x = 2/7
d) x = 2/7 : 3
d) x = 2/21

e) 11x - 4 = 52.1
e) 11x = 52.1 + 4
e) 11x = 56.1
e) x = 56.1/11
e) x = 51/10

f) 2(x - 1) = 4/3
f) 2x - 2 = 4/3
f) 2x = 4/3 + 2
f) 2x = 10/3
f) x = 10/3 : 2
f) x = 5/3
