• Question 1
120 seconds
Q. Solve the Simultaneous Equations: x+y=5; x-y=1
x=2, y=3
x=3, y=2
x=3, y=-2
x=-3, y=2
• Question 2
120 seconds
Q. Solve the Simultaneous Equations: a+b=11; a-b=3
a=7, b = 4
a=-4, b= 7
a=4, b = 7
a=4, b= -7
• Question 3
120 seconds
Q. Solve the Simultaneous Equations: a+b= 3; a-b= -7
a=-2, b = 5
a=2, b = -5
a=2, b = 5
a=-2, b = -5

Inequality
• Question 6
180 seconds
Q. 3x + 2(4x - 4) = 3
4
3
2
1
• Question 7
180 seconds
Q. Translate:
Four times a number plus six IS 30.
4 + 6 = 30
4x + 6 = 30
x + 4 times 6 = 30
30 = 4x
