Solve the system of equations using the substitution method. y=−1+3/8x 2x−5y=6 enter your answer in the boxes. ( , )

The solution of the given system of equation is (8/31,-28/31) and this can be determined by using the substitution method.

Given :

The following steps can be used in order to solve the given system of equations:

Step 1 - Write the given system of equations.

y = −1 + 3/8x   --- (1)

2x − 5y = 6  --- (2)

Step 2 - Now, substitute the value of 'y' in equation (2).

Step 3 - Simplify the above equation.

31x = 8

x = 8/31

Step 4 - Now, substitute the value of 'x' in equation (1).

y = -28/31

y = -1 + 3/8x

2x - 5y = 6

Substitute the first equation into the second equation, since y is already by itself.

2x - 5(-1 + 3/8x) = 6

2x + 5 - 15/8x = 6

2x - 15/8x = 1

16/8x - 15/8x = 1

1/8x = 1 Multiply 8 on both sides to get x by itself

x = 8

Plug x into either of the equations.

y = -1 + 3/8(8)

y = -1 + 3

y = 2

2(8) - 5y = 6

16 - 5y = 6

-5y = -10

y = 2

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
