Question

NEED HELP ASAP PLEASE Given h(x) = 5 - 9x, solve for x if h(x) = -67.

Answer 1

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

Answer 2

We're given with,

⇒h(x) = 5 - 9x

⇒h(x) = -67

Now, We'll make two equations,

⇒h(x) = 5 - 9x ........ (Ⅰ)

⇒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)
