3a + 5b = 26; a + 5b = 22
Solve the following simultaneous equation.
(1) 3a + 5b = 26; a + 5b = 22 3a + 5b = 26 …… (i)a + 5b = 22 ……… (ii) Now by changing the sign of equation (ii) we get– a – 5b = – 22Subtracting equation (ii) from (i) we get2a = 4a = 4/2a = 2Substituting a = 2 […]
Complete the following activity to solve the simultaneous equations.
Given 5x + 3y = 9 ……. (i) 2x + 3y = 12 ……… (ii) Subtracting equation (ii) from (i), we get, (5x + 3y) – (2x + 3y) = 9 – 125x – 2x + 3y – 3y = -33x = -3x = -1 Putting the value of x in equation (i), 5(-1) + […]
