To solve for x:
7x - 5y = 4 Add 5y to both sides
7x = 5y + 4 Divide both sides by 7
x = \(\frac{5}{7}\)y + \(\frac{4}{7}\)
or
x = \(\frac{5y + 4}{7}\)
To solve for y:
7x - 5y = 4 Subtract 7x from both sides
-5y = -7x + 4 Divide both sides by -5
y = \(\frac{7}{5}\)x - \(\frac{4}{5}\)
or
y = \(\frac{7x - 4}{5}\)
