Know More About Corresponding Angles Definition Examples: After solving these two equation we will get the value of x and y. Different type of equations. b.) 2a - 3b = 6 , 5a + b = 10 a.) 5x + y = 12 , 7x - 2y = 21 Example b.) 7x - 6 = 7x + 6. Examples: a.) 5a + 4 -7a = 6a +7 - 8a – 5 Step:2. 4 - 2a = -2a + 2 0 = -2, 0 = 12 ,7=8 Step:1. 7x - 7x = 6 + 6 Step:2. 0 = 12 etc. Step:1. 4 + 5a - 7a = 6a – 8a + 7 - 5 Step: 4. 0 = -2 Step:3. 2a – 2a = 2 - 4
