Question

2 po 3) If in the equation X+2Y=10, the value of y is 6,then the value of X will be....
​

Answer 1

Answer:

We have to create a system with two equations

x−y=6and3x−10=2yx−y=6and3x−10=2y

Find the value of x from An equation and replace it in the other

x=6+yx=6+y

3(6+y)−10=2y3(6+y)−10=2y

Now se have a one-unknown equation. Find the y

18+6y−10−2y=018+6y−10−2y=0

4y−8=04y−8=0

y=2y=2

The value of y is 2. Replace this resulte in the other equation.

x−2=6x−2=6

Now we can find the value of x

X=8

Answer 2

Answer:

x = -2

Step-by-step explanation:

put the value of y as 6 in the equation and after solving you will get the value of x
