0.2x + 0.3y = 1.3 ( x 10 on both sides)
2x + 3y = 13 ....... i
x = (13 - 3y)/2
0.4x + 0.5y =2.3 ( x 10 on both sides)
4x + 5y = 23........ ii
by substitution method
putting the value of x in eq ii
4{(13 - 3y)/2} +5y =23
y = 3
for x
take any equation and put the value of y and x will be
x = 2
2x + 3y = 13 ....... i
x = (13 - 3y)/2
0.4x + 0.5y =2.3 ( x 10 on both sides)
4x + 5y = 23........ ii
