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 = 3

b) −2 + 5 = 6 − x − 2 =

5 = 6 - x

x = 1

c)2 x +4+ 3x −1= 7x − 2 − x =

5x - 6x = -2 - 3

-x = -5

x = 5

e) 1 − 9x = −2 =

-9x = -3

x = 3

f ) 5x −2 = 3x + 1 =

2x = 3

x = 3/2

g) 3x − 3 = x +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 =

-4x = -4

x = 1

Ya está listo ✨

me darías coronita xf ¿?
