X + y = 3
3x + 4y = 3
using substitution how would you get x and y?

The solution is: (x, y) = (9, -7)

Step-by-step explanation:

Step 1: Solve one of the equations for either x = or y = . We will solve second equation for y.

x+y=3

y=3-x

Step 2: Substitute the solution from step 1 into the second equation.

3x+4(3-x)=5

Step 3: Solve this new equation.

3x+4(3-x)=5

3x+12-4x=3

-x+12=3

-x=3-12

x=9

Step 4: Solve for the second variable

y=3-x

y=3-9

y=-7

The solution is: (x, y) = (9, -7)
