Answer:

$x = \frac{5y + 7}{4}$

Step-by-step explanation:

5y - 4x = - 7

5y - 4x + 4x = - 7 + 4x [adding + 4x on both sides ]

5y + 7 = - 7 + 7 + 4x [adding 7 on both sides , - 4x + 4x = 0 ]

5y + 7 = 4x [ -7 + 7 = 0 ]

$\frac{5y + 7}{4} = \frac{4x}{4}$ [ dividing by 4 on both sides ]

$x = \frac{5y + 7}{4}$
