Question

If 3x + y = 10 and y = 4 , then find the value of x 1 point

Answer 1

Answer:

x=2

Step-by-step explanation:

given, y=4

3x+y=10

so,3x+(4)=10

3x+4=10

3x=10-4

3x=6

x=6/3

x=2

now substitute "x" value in equation

3(2)+4=10

6+4=10

Answer 2

The value of x = 2

Given :

• The equation 3x + y = 10

• The value of y = 4

To find :

The value of x

Solution :

Step 1 of 2 :

Write down the given equation

Here the given equation is

3x + y = 10 - - - - - - (1)

Step 2 of 2 :

Find the value of x

The value of y = 4

Putting y = 6 in Equation 1 we get

3x + 4 = 10

⇒ 3x = 10 - 4

⇒ 3x = 6

⇒ x = 6/3

⇒ x = 2

Hence the required value of x = 2
