solve the elimination method substitusion method x+y=5 and 2x-3y=4

Answer»

X+y=5X=5-yput in equation 22(5-y)-3y=410-2y-3y=410-5y=4-5y=-6y=6/5hence X=5-6/5X=25-6/5X=19/5

x+5=5x=5-5x=0

2x-3y=4

thank you for helpmy

x+y=5so, y=5-xputting y value in eq. 22x-3(5-x)=42x-15-3x=4-1x=4+15-1x=19so, x =19
