Question

solve the following pair of linear equations by substitution method. 17x-15y=2 and x+2y=3​

Answer 1

Step-by-step explanation:

7x – 15y = 2 .......(1) x + 2y = 3 ..........(2) Step 1: We pick either of the equations and write one variable in terms of the other. Let us consider the Equation

(2) : x + 2y = 3 and write it as x = 3 – 2y .......(3)

Step 2 : Substitute the value of x in Equation (1). We get 7(3 – 2y) – 15y = 2 i.e., 21 – 14y – 15y = 2 i.e., – 29y = –19 Therefore, y =19/29

Step 3 : Substituting this value of y in Equation (3), we get read
