Solve the system of equations. 5x + y = 9 and 3x + 2y = 4
Solution:
The equations given are
5x + y = 9 --- (1)
3x + 2y = 4 --- (2)
Equation (1) can be written as
⇒ y = 9 - 5x --- (3)
Substituting equation (3) in (2)
⇒ 3x + 2 (9 - 5x) = 4
By further calculation
⇒ 3x + 18 - 10x = 4
⇒ -7x = 4 - 18
⇒ -7x = -14
Dividing both sides by -7
⇒ x = 2
Substitute the value of x in equation (3)
⇒ y = 9 - 5(2)
⇒ y = 9 - 10
⇒ y = -1
Therefore, the solution is x = 2 and y = -1.
Solve the system of equations. 5x + y = 9 and 3x + 2y = 4
Summary:
Solving the system of equations 5x + y = 9 and 3x + 2y = 4 the solution is x = 2 and y = -1.
