What would you do to solve the system?
Molodets [167]

Answer:

To decide whether to add or subtract,  determine if the values of the  coefficients are the same or opposites:

. If the values are the same, subtract the  equations.

• If the values are opposites or additive  inverses, add the equations.

Step-by-step explanation:

Given

12x = 48 - 8y

10x + 8y = 38

Required

How to solve

Options (1) and (2) are incorrect because none of the options eliminate x or y.

For option (3),

- Check for the coefficients of x and y

- If they are the same (sign and value), then subtract; otherwise add

For instance:

12x = 48 - 8y

10x + 8y = 38

Rewrite the second equation

12x = 48 - 8y

10x = 38 - 8y

The coefficient of y are the same, so we subtract;

12x - 10x = 48 - 38 -8y -(-8y)

12x - 10x = 48 - 38 -8y +8y

2x = 10

x= 5

<em>See that y has been eliminated</em>
