Question

by substitution method 6 x minus 2 Y + 10 equal to zero 2 x minus y + 9 = 0 class 10th​

Answer 1

Step-by-step explanation:

the equations are 6 x minus 2 Y + 10 is equals to zero and 2 x minus y + 9 is equals to zero then we can say that X is equals to 2 Y - 10 upon 6 then

2(2y-10/6)-y=-9

2y-10/6-y=-9/2

2y-10/6+9/2=y

2y+10/6=y

y=2.5

substituting the value of y eqn 1

we get, 2x-2.5+9=0

2x=-9+2.5

2x=-7.5 or 75/10 or 25/2 or 12.5

2x=-12.5

x=-12.5/2

x=6.25
