Question

Solve the following pair of linear equation by substitution method: 5(x+3)=3y; 2x-y=0​

Answer 1

Answer:

x = 15

Step-by-step explanation:

Given,

$2x - y = 0 \\y = 2x - equation(1) \\ 5(x + 3) = 3y - equation - (2)$

Substitute equation (1) in (2)

$3y = 5(x + 3) \\ 3(2x) = 5(x + 3) \\ 6x = 5x + 15 \\ 6x - 5x = 15 \\ x = 15$
