Question

a)3+x−2=3+1
b)−2+5=6−x−2
c)2x+4+3x−1=7x−2−x
e)1−9x=−2
f)5x−2=3x+1
g)3x−3=x+3
h)4x−x=2x−5
i)5−x=x−1
j)5−3x = x+1

Answer 1

a) 3 + x - 2 = 3 + 1

x - 2 = 1

x = 1 + 2

x = 3

b) -2 + 5 = 6 - x - 2

5 = 6 - x

x = 6 - 5

x = 1

c) 2x + 4 + 3x - 1 = 7x - 2 - x

5x + 3 = 6x - 2

- x = -5

x = 5

e) 1 - 9x = -2

-9x = -2 - 1

-9x = -3

x = 1/3

f) 5x - 2 = 3x + 1

5x = 1x - 3x = 1 + 2

2x = 3

x = 3/2

g) 3x − 3 = x + 3

3x - x = 3 + 3

2x = 6

x = 3

h) 4x − x = 2x − 5

3x = 2x - 5

x = -5

i) 5 − x = x − 1

-2x = -6

x = 3

j) 5 − 3x = x + 1

-3x - x = 1 - 5

-4x = -4

x = 1
