Question

What is the solution for

2x + y = 4

3x + 3y =9

Answer 1

X=3 y = 5

Explanation:

Step 1) Solve the first equation for y

Step 2) Substitute 3 x − 4 for y in the second equation and solve for x

Step 3) Substitute 3 for x in the solution to the first equation at the end of Step 1 and calculate y

The solution is:

x = 3 and y = 5 or ( 3 , 5 )
