Question
$7 + 4y = - 5$

Answer

$7 + 4y = -5$ Subtracting $7$ from both sides,
we get $7 + 4y - 7 = -5 -7 4y = -12$ Dividing both sides by $4,$
we get $\text{y}=\frac{-12}{4}$ $\text{y}=-3$ Verification: Substituting $y = -3 in L.H.S.,$
we get $L.H.S. = 7 + 4y = 7 + 4(-3) = 7 - 12 = -5,$
and $R.H.S. = -5 L.H.S. = R.H.S.$
Hence, verified.

A doctor reports blood pressure in millimetres of mercury $(mm \ Hg)$ as a ratio of systolic blood pressure to diastolic blood pressure $($such as $140$ over $80)$. Systolic pressure is measured when the heart beats and diastolic pressure is measured when it rests. Refer to the table of blood pressure ranges for adults.
    Blood Perssure Ranges  
  Normal Prehypertension Hypertension
Systolic Under $120\ mm \ Hg$ $120 - 139\ mm \ Hg$ $140\ mm \ Hg$ and above
Diatolic Under $80\ mm \ Hg$ $80 - 89\ mm \ Hg$ $90\ mm \ Hg$ and above
