Question

4. For drawing the graph of 3x + 7y = 27, if y = 3. what is the value of x
A.2
B. 13
C.9​

Answer 1

Answer:

x would be 2

3x +7y = 27

3x = 27 -7y

x =( 27 -7y) /3

putting the value of y

x = (27-7(3)) /3

x= (27-21) /3

x= 6/3

x=2

Answer 2

Given - Equation

Find - Value of x

Solution - The value of x is A. 2.

Keeping the value of variable y in the given equation. The new equation that will form is -

3x + 7*3 = 27

Performing multiplication to find the value of x.

3x + 21 = 27

Performing subtraction to find the value of x.

3x = 27 - 21

3x = 6

Performing division to find the value of x.

x = 6/3

x = 2

Thus, the value of x, as per given data, is A. 2.
