Question

Solve system of equations algebraic ally
3x-y=0
5x+2y=22

Answer 1

Answer:

x=2 is a solution.

Step-by-step explanation:

We have two equations:

3x - y = 0 --------- (1)

5x + 2y = 22 ----------(2)

3x - y = 0

=> 3x = y

Substituting y in (2) :

5x + 2(3x) = 22

=> 5x + 6x = 22

=> 11x = 22

=> x = 2

Answer 2

Answer:

$3x - y = 0 \\ 3x = y \\ x = \frac{y}{3} \\ 5x + 2y = 22(given) \\ \\ putting \: x = \frac{y}{3} \\ \frac{5y}{3} + 2y = 22 \\ \frac{5y + 6y}{3} = 22 \\ 5y + 6y = 66 \\ 11y = 66 \\ y = 6. \\ y = 6putting \: in \: eq \: 1 \\ x = \frac{6}{3 } = 2\\ hence \: x = 2 \: and \: y = 6$
