Math Problem Statement

Solve. 2x - 6y = -16, x + 3y = 16

Solution

The image you've provided contains a system of equations that we need to solve:

  1. 2x6y=162x - 6y = -16
  2. x+3y=16x + 3y = 16

Step 1: Solve the second equation for xx

From the second equation x+3y=16x + 3y = 16, we can solve for xx:

x=163yx = 16 - 3y

Step 2: Substitute into the first equation

Now substitute x=163yx = 16 - 3y into the first equation 2x6y=162x - 6y = -16:

2(163y)6y=162(16 - 3y) - 6y = -16

Step 3: Simplify and solve for yy

Now expand and simplify the equation:

326y6y=1632 - 6y - 6y = -16

3212y=1632 - 12y = -16

Subtract 32 from both sides:

12y=48-12y = -48

Now divide both sides by -12:

y=4y = 4

Step 4: Substitute y=4y = 4 into the second equation to solve for xx

Substitute y=4y = 4 back into x+3y=16x + 3y = 16:

x+3(4)=16x + 3(4) = 16

x+12=16x + 12 = 16

Subtract 12 from both sides:

x=4x = 4

Final Answer:

The solution is x=4x = 4 and y=4y = 4.

Thus, the solution in ordered pair form is (4,4)(4, 4).
