This question is from linear equations in two variables in which we have been asked to find the value of variables x and y from the equations 0.3x+0.5y=0.5, 0.5x+0.7y=0.74
Kindly solve these equations
RS Aggarwal, Class 10, chapter 3B, question no 14
Equation (1)×30:15x+21y=22.2
Equation (2)×50:15x+25y=25
Subtract two equations ;
⇒4y=14/5
⇒y=7/10
Substitute y in equation 1, we get ;
⇒x=1/2
