84+92+87+104=367
500-367=133

Answer:
The solution is obtained by adding the two equations.
The solution is: (x, y) = (
,
)
Step-by-step explanation:
We are given two equations with two variables. The strategy is to eliminate one variable and solve for both the variables.
The two equations are:


Adding both the equations, we get:



Substituting the value of 'x', we get the value of y.
We substitute in (2). [Can be substituted in any equation].
We get: y = 2x - 1



So, we get the corresponding values of x and y which is the solution of the two equations.
Answer:
$2
Step-by-step explanation:
4 - 2 = 2
That is true because if you use the surface area formula, 2(wl+hl+hw), you'll get 250.
