Question

if x-y=10 and x=2y, then answer will be

Answer 1

x-y=10
2y-y=10
y=10
x=2y
x=2*10
x=20

Answer 2

Answer:

The values of x and y are 20 and 10 respectively.

Step-by-step explanation:

Linear equations:

• Linear equations are the equations of first order.
• When the equation have a homogeneous variable of degree 1 then it is called a linear equation in one variable.
• A linear equation can have more than one variable. When a linear equation has more than one variable it is called as a linear equation in two variables.

Solving equations:

Given equations are

x-y = 10 and x = 2y

Consider x-y = 10 -------------(I)

x = 2y -------------(II)

substitute (II) in (I)

2y - y = 10

y = 10

now substitute y = 10 in equation (II)

x = 2(10) = 20

x = 20

Hence by solving the given equations we get the values of x an y are 20 and 10 respectively.
