8х + 7y= -5
X= -3y - 7

x = 2

y = -3

Step-by-step explanation:

Step 1: Write systems of equation

8x + 7y = -5

x = -3y - 7

Step 2: Solve for y

Substitute 2nd equation into 1st: 8(-3y - 7) + 7y = -5Distribute 8: -24y - 56 + 7y = -5Combine like terms: -17y - 56 = -5Add 56 to both sides: -17y = 51Divide both sides by -17: y = -3

Step 3: Solve for x

Substitute y to find x: x = -3(-3) - 7Multiply: x = 9 - 7Subtract: x = 2

Step 4: Check

Plug in x, y into an original equation to verify it's a solution.

2 = -3(-3) - 7

2 = 9 - 7

2 = 2

Yes of course i will indeed you with your problem.

< i think this is the answer unless i did my math wrong
