Question

-x+2y=0 ; 10x+15y=105

step by step elimination and substitution. please.​

Answer 1

Step-by-step explanation:

Here, -x + 2y =0

= -x = -2y

so, x = 2y

ATQ, 10x + 15y =105

(10×2y) + 15y = 105

20y + 15y = 105

35y = 105

y = 105÷35 = 3

now, as, x = 2y

x = 2 × 3 = 6

So, x = 6 and y = 3

hope it helps you:)
