Step-by-step explanation:

7x+8x+2 = 18x-27-8

15x+2 = 18x-35

2+35 = 18x- 15x

37 = 3x

37/3 = x

x = 12.34

  • Given the equation

________________________________________________________________________

7x + 8(x +  \frac{1}{4} ) = 3(6x - 9)  - 8

Let us now start solving this equation for X

 =  &gt;   7x + 8(x +  \frac{1}{4} ) = 3(6x - 9) - 8 \\  \\  =  &gt;7x + 8( \frac{4x + 1}{4} ) = 3(6x - 9) - 8 \\  \\  =  &gt; 7x + 8 \times  \frac{4x + 1}{4}  = 18x - 27 - 8 \\  \\  =  &gt; 7x + 2(4x + 1) = 18x - 35 \\  \\  =  &gt; 7x + 8x + 2 = 18x - 27 \\  \\  =  &gt; 15x - </strong><strong>1</strong><strong>8x =  - 35 - 2 \\  \\  =  &gt; </strong><strong>3</strong><strong>x = 3</strong><strong>7</strong><strong> \\  \\  =  &gt; x =  \frac{33}{7}

So by solving the given equation we find the value of X is 37/3

Or the answer in the decimal form is also correct we can find the decimal form of the answer by dividing 37 by 3 so the answer is

12.3
