Question 1

1 mark

Solve the following equation to find the value of \(x\):
\(4x + 7 = 23\)

Question 2

1 mark

A rectangular field has a length of \( (2x + 3) \) metres and a width of \( (x - 1) \) metres.
Given that the area of the field is \( 42 \text{ m}^2 \), show that \( 2x^2 + x - 45 = 0 \) and find the value of \( x \).

Question 3

1 mark

Solve the following simultaneous equations:
\(2x + y = 7\)
\(3x - y = 8\)

Question 4

1 mark

Expand the following expression:
\(3(2x - 5)\)

Question 5

1 mark

Find the value of \(x\) in the following linear equation:
\(3(x - 4) = 15\)

Question 6

2 marks

Given that \(y = 4x + 3\), find the value of \(y\) when \(x = 6\).

Write your answer out first, then check it against the worked solution.

Question 7

3 marks

Solve the following equation for \(x\):
\(7x - 2 = 3x + 10\)

Write your answer out first, then check it against the worked solution.

Question 8

5 marks

Solve the following simultaneous equations:
\( 3x + 2y = 16 \)
\( 2x - y = 6 \)
