Solve the equation

Question

Solve: x+y=2

          3x+2y5 

using the substitution method

Answer 1

Y= 2 - x

 

substitute this value for y into the  second equation

 

3x + 2(2-x) = 5

 

3x+4-2x=5

 

x= 1

 

Finally substitute this value for X to find y

 

y = 2-1 

 

= 1

 

Those are our values for X and y.
