Question

h) (8-5+4)+x-15=6
i) x-3-5-7-16=1
j) 10+x-6+4=20
k)7-x+5=4
l) (6-4+x)-2=8

Answer 1

h) (8-5+4)+x-15 = 6
    3+4+x = 6+15
    7+x = 21
    x = 21-7
    x = 14

i) x-3-5-7-16 = 1
   x-8-23 = 1
   x-31 = 1
   x = 31+1
   x = 32

j) 10+x-6+4 = 20
    10+x-2 = 20
    10+x = 20+2
    10+x = 22
    x = 22-10
    x = 12

k) 7-x+5 = 4
    7-x = 4-5
    7-x = -1
    x = 7-(-1)
    x = 7+1
    x = 8

l) (6-4+x)-2 = 8
   2+x = 8+2
   2+x = 10
   x = 10-2
   x = 8

Sper ca te-am ajutat.

Answer 2

h)(8-5+4)+x-15=6
(3+4)+x=6+15
7+x=21
x=21-7
x=14
I)x-3-5-7-16=1
x-3-5-7=1+16
x-3-5=17+7
x-3=24+5
x=29+3
x=32
j)10+x-6+4=20
10+x-6=20-4
10+x=16+6
x=22-10
x=12
k)7-x+5=4
7-x=4-5
-x=-1+7
-x=6
x=-6
l)(6-4+x)-2=8
(2+x)=8+2
x=10-2
x=8
