Question:
Solve the following linear equation and so find the value of x
The questions are as follows:
1. Solve the following linear equation and so find the value of x:
3x + 4 = 5x - 10
2. Solve the following pair of simultaneous equations using either the method of elimination or substitution:
(i) 5x = -3y + 11
(ii) y = 4x - 19
3. Determine whether the solution (given in square brackets) satisfies the following simultaneous equations:
(i) -7x = 2y + 3
(ii) 5x = -y - 12 [x = -7 and y = 23]
4. Simplify the following subtraction so that involves only one algebraic fraction
5x 3y
2z 5x
