Answer 1

Given:

1-Simplyfy 6x -4y +3x+8y

2-Solve 3(x+6)-4=6 x +2

X?

Required:

To simplify the given equation

Step-by-step explanation:

`\begin{gathered} 6x-4y+3x+8y \\ \\ group\text{ like terms} \\ \\ =6x+3x-4y+8y \\ \\ Add\text{ similar elements:} \\ \\ =9x-4y+8y \\ \\ Add\text{ similar elements} \\ \\ =9x+4y \end{gathered}`
`\begin{gathered} 3\left(x+6\right)-4=6x+2x \\ \\ Add\text{ similar elements} \\ \\ 3\left(x+6\right)-4=8x \\ \\ expand \\ \\ 3x+14=8x \\ \\ subtract\text{ 14 from both sides} \\ \\ 3x+14-14=8x-14 \\ \\ 3x=8x-14 \\ \\ subtract\text{ 8x from both sides} \\ \\ 3x-8x=8x-14-8x \\ \\ -5x=-14 \\ \\ =divide\text{ both side by 5} \\ \\ (-5x)/(-5)=(-14)/(-5) \\ \\ x=(14)/(5) \end{gathered}`
