Answer 1

g) x= 1+13=14

h) 2x=2-2

2x=0 => x=0

i) 5x-2x=18-6

3x=12

x=4

j) -5x-x=8+4

-6x=12

x= -2

k) x+3+2=10

x+5=10

x=5

l) 3-4+x=1

-1+x=1

x=1+1=2

Answer 2

g)

$x = 1 + 13 \\ x = 14$

h)

$- x + 3x = 2 - 2 \\ 2x = 0 \\ x = 0 \div 2\\ = 0$

i)

$5x - 2x = 18 - 6 \\ 3x = 12 \\ x = 12 \div 3 \\ x = 4$

j)

$- 5x - x = 8 + 4 \\ - 6x = 12 \\x = 12 \div ( - 6) \\ x = - 2$
