Question 4 (iv) hich of the following pairs of linear equations are consistent/ inconsistent? If consistent, obtain the solution graphically: 2x - 2y - 2 = 0, 4x - 4y - 5 = 0
a1a2=24=12 b1b2=−2−4=12 and c1c2=25 Hence, a1a2=b1b2≠c1c2 Therefore, these linear equations are parallel to each other and thus, have no possible solution. Hence, the pair of linear equations is inconsistent.
