Question # 1
Solve the simultaneous equations:
5x + 2y = 9
3x + 2y = 7
Question # 2
Solve the simultaneous
equations:
3b - 4c = 7
b + 4c = 13
Question # 3
Solve the simultaneous equations:
5x - 6y = 27
3x - 2y = 13
Question # 4
Solve the simultaneous equations
2x - 3y = 7
5x + 4y = 6
Question # 5
Solve the following
simultaneous equations:
3x + 8y = - 34
2x - 39 = 7y
Question # 6
Solve the simultaneous
equations
13 x - 6 y = 20
7x + 4 y = 18
Question # 7

4 5
Question # 9
Solve the simultaneous equations
1
- (2x+1) + y = 1
3
3x + 4 = 2(1 - y)
Question # 10
The total cost of the
tickets to a show for 4 adults and 6 children is $32 while the cost for 3 adults
and 2 children is $19. Let the cost of an adult's ticket be $x and the cost of a
child's ticket be $y.
a) Write down two simultaneous equations in x and y.
b) Hence solve the two simultaneous equations to find the cost of an adult's
ticket and that of a child's ticket
Question # 11
ABC is an
equilateral triangle, ie. all its sides are equal in length.
a) Form 2
simultaneous equations from the information given.
b) By solving the
simultaneous equations, find the value of x and y.
c) Hence, find the
perimeter of the triangle.
Question # 12

positive numbers is 60. If one number is greater than the
other by 4,
find the two numbers
