Question

5x+2y=13;4x-3y=15 linear equation in two.​

Answer 1

Step-by-step explanation:

We pick either of the equations and write one variable in terms of the other.

Let us consider the equation 5x−2y=13 and write it as

$\sf{ \red{ x \: = \frac{13 - 2y}{5}}}$

Substitute the value of x in equation 4x+3y=15. We get

( attached in image)

Therefore, y=1

Substituting this value of y in the equation 5x−2y=13, we get

$\big \sf{ \red{ \: 5 \: x - 2 = 13}}$

$\big \sf{ \red{ \: 5 \: x = 13 + 2 = 15}}$

$\huge \sf{ \red{ x \: = 3}}$

Hence, the solution is x=3,y=1.
