18
11
12

Q 2: Some number decreased by 50 gives 35.
x + 35 = 50
x - 50 = 35
x + 50 = 35
x = 35 - 50

Q 3: 3x - 5 = 25, find the value of x.
Answer:

Q 4: Some number added to 15 gives 20.
x = 15 + 20
x + 15 = 20
x + 20 = 15
15x = 20

Q 5: Solve: 45a + 15 = 30a - 15
Answer:

Q 6: Solve the following linear equations.
x - 2y + 3z = 9
-x + 3z = -4
2x - 5y + 5z = 17

x = -1, y = 1 and z = 2
inconsistent system
x = 51/3, y = -1/8 and z = -5/8
x = 53/8, y = 1/8 and z = 7/8

Q 7: 3(3 + 5) + 1 = 25
True
False

Q 8: Solve the following linear equations.
a + b + c = 10
a + 2b + 3c = 5
2a + b + 5c = 4

a = 27/2, b = -10/2 and c = -7/2
a = 15, b = 2 and c = -8
a = 54/5, b = 17/5 and c = -21/5
inconsistent system
