Question

solve simultaneous equation :2y-x=0;10x+15y=150 who will help me I will do what you want ​

Answer 1

Answer:

x=6 and y=3

Step-by-step explanation:

The given equations can be solved by substitution method.

2y - x=0

2y = x

..x=2y

10x + 15y = 105 -(1)

Substitute x value in (1)

10x + 15y = 105

+ 10(2y) + 15y = 105

20y + 15y = 105

35y = 105

y =

» y = 3

Sub y= 3 in x

x = 2y

> x= 2(3)

> x = 6

..x=6 and y = 3.

I hope it helps you
