Answer 1

a)
2x = 16
x = 8

b)
y + 5 = 9
y = 9 - 5
y = 4

c)
3z - 1 = 14
3z = 14 + 1
3z = 15
z = 15 : 3
z = 5

d)
7 = 19 - 2x
7 - 19 = - 2x
-12 = - 2x ( - 1)
12 = 2x
2x = 12
x = 12 : 2
x = 6

e)
10 - 4y = y
10 = y + 4y
10 = 5y
5y = 10
y = 10 : 5
y = 2

f)
3 - z = 5z - 15
- z - 5z = - 15 - 3
- 6 z = -18 ( - 1)
6z = 18
z = 18: 6
z = 3

Answer 2

a)
$2x=16 \\ x=16\div2 \\ x=8$

b)
$y+5=9 \\ y=9-5 \\ y=4$

c)
$3z-1=14 \\ 3z=14+1 \\ 3z=15 \\ z=15\div3 \\ z=5$

d)
$7=19-2x \\ 2x=19-7 \\ 2x=12 \\ x=12\div2 \\ x=6$

e)
$10-4y=y \\ -4y-y=-10 \\ -5y=-10 \\ 5y=10 \\ y=10\div5 \\ y=2$

f)
$3-z=5z-15 \\ -z-5z=-15-3 \\ -6z=-18 \\ 6z=18 \\ z=18\div6 \\ z=3$
