Solve graphically please send me by solving and clicking photo plzzzz​
Delicious77 [7]

Answer:

Subtract 5x from both sides of the equation.

7y=1−5x

x+4y=−5

Divide each term by 7 and simplify.

y=17−5x/7

x+4y=−5

Subtract x from both sides of the equation.

y=1/7−5x/7

4y=−5−x

y=1/7−5x/7

Divide each term by 4 and simplify.

y=1/7−5x/7

y=−5/4−x/4

y=1/7−5x/7

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution. (3,−2)
