2x+ 3y = 16  3x  + 2y = 15 solve this equation by elimination 

To solve the system of linear equations using the elimination method, we will:

1. Eliminate one variable by multiplying the equations so that their coefficients align for one of the variables.
2. Subtract or add the equations to eliminate that variable.
3. Solve for the remaining variable.
4. Substitute the value of the found variable into one of the original equations to find the second variable.

The system of equations is:
\[
2x + 3y = 16 \quad (1)
\]
\[
3x + 2y = 15 \quad (2)
\]

### Step 1: Make the coefficients of \(x\) or \(y\) equal
Let's eliminate \(x\). To do this, we'll multiply the first equation by 3 and the second equation by 2 to align the coefficients of \(x\).

Multiply (1) by 3:
\[
6x + 9y = 48 \quad (3)
\]

Multiply (2) by 2:
\[
6x + 4y = 30 \quad (4)
\]

### Step 2: Subtract the equations to eliminate \(x\)
Now subtract equation (4) from equation (3):
\[
(6x + 9y) - (6x + 4y) = 48 - 30
\]
This simplifies to:
\[
5y = 18
\]
Solve for \(y\):
\[
y = \frac{18}{5} = 3.6
\]

### Step 3: Substitute the value of \(y\) into one of the original equations
Substitute \(y = 3.6\) into equation (1):
\[
2x + 3(3.6) = 16
\]
\[
2x + 10.8 = 16
\]
Solve for \(x\):
\[
2x = 16 - 10.8
\]
\[
2x = 5.2
\]
\[
x = \frac{5.2}{2} = 2.6
\]

### Final Solution:
\[
x = 2.6, \quad y = 3.6
\]
