Question

a) 8x=24
b) x+8=24
c) 3x=-12
d) 3+x=-12
e) 5+2x=11
f) 5+2+x=11
g) 2+x-2x=7
h) 2x-2+x=7

Answer 1

a)
8 x = 24 
x = 24 : 8 
x = 3 
 
b)
x + 8 = 24
x = 24 - 8 
x = 16 

c)
3 x = - 12
x = ( - 12) : 3 
x = - 4 

d)
3 + x = - 12
x = - 12 - 3 
x = - 15 

e) 
5 + 2 x = 11
2 x = 11 - 5 
2 x = 6 
x = 6 : 2 
x = 3 

f)
5 + 2 + x = 11
x = 11 - 7 
x = 4 


g)
2 + x - 2 x = 7
- x = 7 - 2 
x = - 5 

h)
2 x - 2 + x = 7
3 x = 7 + 2 
3 x = 9 
x = 9 : 3 
x = 3 

Answer 2

a)8 x=24
X=24:8
X=3
b) x+8=24
X=24-8
X=16
c)3 x=-12
X=-12:3
X=-4
d)3+ x=-12
X=-12-3
X=-15
e)5+2 x=11
2 x=11-5
X=6:2
X=3
f)5+2+ x=11
7+ x=11
X=11-7
X=4
g)2 + x-2 x=7
- x=7-2
X=-5
h)2 x-2+ x=7
3 x=7+2
X=9:3
X=3
