Question

solve the
following pair of linear
equation by the substitution
method-
x + y = 7
12x + 5y = 7​

Answer 1

Answer:

Solve each of the following system of equations by eliminating x (by substitution) : (i) x + y = 7. 2x – 3y = 11. (ii) x + y = 7. 12x + 5y = 7.

Step-by-step explanation:

Algebraic methods given below yield accurate answers. ... Substitute this value of y in the second equation. ... (i) x + y = 7 and 2x – 3y = 11, (ii) x y = 7 and 12x + 5y = 7, (iii) 2x – 7y = 1 ...
