We're given with,

h(x) = 5 - 9x

h(x) = -67

Now, We'll make two equations,

h(x) = 5 - 9x ........ ()

h(x) = -67 ......... (ⅠⅠ)

As, both the equations which we formed are equal, So, we'll equate both of them,

5 - 9x = -67

-9x = -67 - 5 (Combining like terms)

-9x = -72 (Since, (-) is common in L.H.S & R.H.S we'll cancel it out & we will get the values positive)

x = 72/9 (Transposing 9 to R.H.S)

x = 8 (Required Answer)

Solution :

Given :

h(x) = 5 - 9x - equation (1)

h(x) = -67 - equation (2)

since, both of them are equal, let's equate :

  • 5 - 9x = -67

  • -9x = -67 - 5

  • -9x = -72

  • x = (-72) ÷ (-9)

  • x = 8
