# Let us solve the following simultaneous equations in two variables by the method of substitution.

7x – 5y = 2

Answer :

Given … (1)

And 7x – 5y = 2 … (2)

Expressing x of equation (1) in terms of y,

… (3)

Substituting (3) in (2),

⇒ 7x – 5y = 2

∴ y = 8

Substituting y value in (3),

∴ x = 6

∴ By solving, we get x = 6 and y = 8.
