Question

# Solve the following by using the method of substitution

Y = 4X+2

Y = X+8

Hint:

### find x by substituting y (in terms of x) in the equation and find y by substituting value of x in the equations.

## The correct answer is: x = 2 ; y =10

### Ans :- x = 2 ; y =10

Explanation :-

⇒ y = 4x + 2 — eq 1

⇒ y = x + 8—- eq 2

Step 1 :- find x by substituting y = 4x + 2 in eq 2.

4x + 2 = x + 8 ⇒ 4x – x = 8 - 2

⇒ 3x = 8 - 2 ⇒ 3x = 6

⇒ x =2

Step 2 :- substitute value of x and find y

⇒ y = x + 8 ⇒ y = 2 + 8

∴ y= 10

∴ x = 2 and y = 10 is the solution of the given pair of equations.
