2x+3y=12

x+y=5

1 answer

To solve the system of equations given by:

  1. \( 2x + 3y = 12 \) (Equation 1)
  2. \( x + y = 5 \) (Equation 2)

We can use the substitution or elimination method. Here, I'll use the substitution method.

From Equation 2, we can express \( x \) in terms of \( y \):

\[ x = 5 - y \]

Now, we can substitute this expression for \( x \) into Equation 1:

\[ 2(5 - y) + 3y = 12 \]

Expanding this, we get:

\[ 10 - 2y + 3y = 12 \]

Combining like terms:

\[ 10 + y = 12 \]

Now, isolate \( y \):

\[ y = 12 - 10 \] \[ y = 2 \]

Now that we know \( y \), we can substitute back to find \( x \):

\[ x = 5 - y = 5 - 2 = 3 \]

Thus, the solution to the system of equations is:

\[ x = 3, \quad y = 2 \]

So, the final answer is:

\[ (x, y) = (3, 2) \]
