Answer:

Step-by-step explanation:

Let's solve the first equation for either x or y. I'll do it for x.

Begin by subtracting 5y.

Now divide by 5.

Simplify:

Now substitute x in the second equation for this value.

Distribute;

Add 6

Combine like terms;

Divide by -10.

Take this value of y and replace it in the first equation to find the value of x.

Answer:
x - 8y = - 56
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y =
x + 7
Multiply through by 8 to clear the fraction
8y = x + 56 ( subtract 8y from both sides )
0 = x - 8y + 56 ( subtract 56 from both sides )
- 56 = x - 8y, that is
x - 8y = - 56 ← in standard form
