20 points Determine whether the statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement.

To solve the system below by substitution, replace y in the second equation with 7−6x.

6x−y=7

2x+y=5

This statement is true.

This statement is false. To solve the system by substitution, replace x in the second equation with 7−6x.

This statement is false. To solve the system by substitution, replace y in the first equation with 7−6x.

This statement is false. To solve the system by substitution, replace y in the second equation with 6x−7.

==> False.

This statement is false. To solve the system by substitution, replace y in the first equation with 7−6x.

==> False

This statement is false. To solve the system by substitution, replace y in the second equation with 6x−7.

==> True.

From the first equation, 6x-y=7

y= 6x-7

i think ur answer is   (3,-1)

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
