This exercise contains all three types of simultaneous equations. Look for the simplest way to solve the following equations:
Question 4
| (a) | \( 4x - 3y = 36\) | (b) | \( 5x - 2y = 0\) | (c) | \( 6x + 3y = 15\) | (d) | \( 7x + 3y = 38\) |
| \( 3x - y = 22\) | \( 15x + 4 = 50\) | \( 5x - 3y = 29\) | \( 4x + 2y = 20\) | ||||
| (e) | \( 5x - 3y = 60\) | (f) | \( 2x - y = -8\) | (g) | \( 2x - 7y = 20\) | (h) | \( 8x - 5y = 18\) |
| \( 4x + 6y = 6\) | \( 3x + 5y = 27\) | \( 4x + 3y = -11\) | \( 4x + 7y = -29\) | ||||
| (i) | \( 21x - 4y = 30\) | (j) | \( 7x - 4y = 2\) | (k) | \( 4x - 3y = -8\) | (l) | \( 10x - 2y = 5\) |
| \( 7x + 3y = 23\) | \( 4x + 7y = 3\) | \( 8x + 4y = 14\) | \( 5x + 3 = 1.5\) | ||||
