To solve the system of equations:
- 1. 3x + 2y = 14
- 2. 5x + y = 32
We can use the method of substitution or elimination. Here, we will use substitution for clarity.
First, let’s solve the second equation for y:
y = 32 - 5x
Now, substitute this expression for y into the first equation:
3x + 2(32 - 5x) = 14
This simplifies to:
3x + 64 - 10x = 14
Combine like terms:
-7x + 64 = 14
Now, isolate x:
-7x = 14 - 64
-7x = -50
x = rac{50}{7}
Now that we have x, we can substitute back to find y. Using our expression for y:
y = 32 - 5(rac{50}{7})
Calculating that gives:
y = 32 - rac{250}{7}
Convert 32 to a fraction:
y = rac{224}{7} - rac{250}{7} = -rac{26}{7}
Therefore, the solution to the system of equations is:
- x = rac{50}{7}
- y = -rac{26}{7}
In decimal form, this is approximately:
- x ≈ 7.14
- y ≈ -3.71
This gives us the points where the two equations intersect on a graph.
