The value of x = [tex]\frac{-58}{3}[/tex].

Step-by-step explanation:

Given,

4.5(30 - x) + 15 = 95 – 1.5(5x + 12)

To find value of x.

4.5(30 - x) + 15 = 95 – 1.5(5x + 12)

or, 4.5×30 - 4.5×x = 95 - 1.5×5x-1.5×12  [ a(b+c) = ab+ac This property is known as distributive property]

or, 135 - 4.5x = 95 - 7.5x - 18

or, 7.5x - 4.5x = 95 - 18 - 135 [ Taking the variables in LHS and all the constant terms in RHS]

or, 3x = -58

or, x = [tex]\frac{-58}{3}[/tex]

Here is the value of x.
