Understand the problem

Solve for x:

8+x3(x2)=5(2+x)4+3x -8+x-3(x-2)=5(2+x)-4+3x

Step-by-step solution

First, we will expand the parentheses on both sides by multiplying their contents by the number outside:

8+x3×x+(3)×(2)=5×2+5×x4+3x -8+x-3\times x+(-3)\times(-2)=5\times2+5\times x-4+3x

8+x3x+6=10+5x4+3x -8+x-3x+6=10+5x-4+3x

Now we collect like terms on both sides:

22x=6+8x -2-2x=6+8x

We move 8x to the left and -2 to the right side, remembering to leave the plus and minus signs unchanged accordingly:

2x8x=6+2 -2x-8x=6+2

We add the terms together:

10x=8 -10x=8

Finally, we divide both sides by negative 10:

10x10=810 \frac{-10x}{-10}=\frac{8}{-10}

x=810 x=-\frac{8}{10}

Final Answer

810 -\frac{8}{10}
