The solution is x=,y=

Answer 1

Solve for x or y and substitute into the other equation.

Answer 2

can you show me an example?

Answer 3

For example
3x + 2y = 5
4x +5y=10
From first equation 3x=5-2y
x = (5-2y)/3
Substitute x value in other equation
4[(5-2y)/3]+5y=10 You have only y values. Solve for y

Answer 4
