Math Problem Statement

Q1. The solution of pair of equations 2x-3y=1 and 4x-2y= 6, is (1) (3, 1) (3) (2,4) (2) (2, 2) (-1,2)

Solution

We are given the system of equations:

  1. 2x3y=12x - 3y = 1
  2. 4x2y=64x - 2y = 6

Step 1: Solve using substitution or elimination

We'll use the elimination method. First, we'll multiply the first equation by 2 to align the coefficients of xx.

2(2x3y)=2(1)    4x6y=22(2x - 3y) = 2(1) \implies 4x - 6y = 2

Now, we subtract this from the second equation:

(4x2y)(4x6y)=62(4x - 2y) - (4x - 6y) = 6 - 2

This simplifies to:

4y=4    y=14y = 4 \implies y = 1

Step 2: Substitute y=1y = 1 into one of the original equations

We'll substitute y=1y = 1 into the first equation:

2x3(1)=1    2x3=1    2x=4    x=22x - 3(1) = 1 \implies 2x - 3 = 1 \implies 2x = 4 \implies x = 2

Solution:

The solution is (x,y)=(2,1)(x, y) = (2, 1).

Since this doesn't match any of the provided options, there may be a misprint in the choices. However, based on the solution, the answer is (2,1)(2, 1).

  5. Solve 3x+4y=103x + 4y = 10 and 2x5y=12x - 5y = 1.

Tip: Always check the solution by substituting the values of xx and yy back into the original equations.
