Question

Use the substitution method to solve the following system of equations.
x + y = 3
2x + 2y = 10

Answer 1

x + y = 3 ---(I)
2x + 2y = 10 ---(II)

Rearranging (I) we get x = 3-y

Now substitute x = 3-y in (II) and solve, you will get value of y
put that in (I) and you will get the value of x
then write the solution as an ordered pair.

Answer 2

ok thankss
