3 − 5(x + 2) = 3(x + 1) + 6 In your own words, explain the process for solving this equation. Please include your work at each step of the process along with the final answer.
First reminder the student about order of operations. 3-5*(x+2)=3*(x+1)+6 first step multiply the coefficients of the parenthetical expressions first. 3-5x-10=3x+3+6 Next collect similar terms. -5x-7=3x+9 Next move the variables to the same side. +5x=+5x 7=8x+9 now move the nine across 7-9=8x -2=8x -2/8=x -1/4=x
Move all terms not containing x to the right side of the equation. -5(x+2)=3x+6 Multiply -5 by each term inside the parentheses. -5x-10=3x+6 Move terms not containing x to the right side of the equation. -8x-10=6 Move all terms not containg x to the righthand side of the equation. -8x=16 Divide each term in the equation by -8. x=-2
You distribute the numbers outside the parenthesis first: 3-5x-10=3x+3+6 now you add up like term on each side: -7-5x=3x+9 add five x to each side: -7=8x+9 and subtract 9 from each side: -16=8x now isolate the x by dividing both sides by 8: -2=x ta dah!
@Mad is kinda similar to mines. but i showed more work :]
Thank you all so much!
x=-2
