2.a)
x-9=5
x=5+9
x=14

2.b)
4(a+2)=2(a-8)
4a+8=2a-16
4a-2a=-16-8
2a=-24
a=-24:2
a=-12

1. a. x + 11 = 11
b. t – 12 = 36
c. y/6 = 15

2.a. x – 9 = 5
=> x = 5 + 9
=> x = 14
b. 4(a+2)= 2(a-8)
=> 4a + 8 = 2a – 16
=> 4a – 2a = -16 – 8
=> 2a = -24
=> a = -24/2
=> a = -12
c. 2 + 11/b = 7 1/2
=>11/b = 7 1/2 – 2
=>11/b = 5 1/2
=>11/b = 11/2
=> b = (11 x 2)/11 = 22/11
=> b = 2

3. a. 3x + 2 > 4x – 5
=> 3x – 4x > – 5 – 2
=> -x > -7
=> x < -7/-1
=> x < 7
b.
