Given the equation:
x[x+2(3x-7)]=22x-65
Simplify the equation.
Solution:
In order to simplify the equation, we start first by multiplying 2 to each value inside the parenthesis.
x[x+2(3x-7)]=22x-65
x[ x + 6x - 14]=22x-65
x[ 7x - 14]= 22x - 65
The next step is to distribute x to each value inside the bracket.
7x^2 - 14x = 22x - 65
Transpose 22x - 65 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
= 7x^2 -14x - 22x + 65
= 7x^2 -36x + 65
Final answer:
= 7x^2 -36x + 65
