Given the equation 7(x + 2) = 2x − 1, solve for the variable. Explain each step and justify your process. Jeff solved a similar equation below. Is Jeff's solution correct? Explain why or why not. 3x − 2 = 5(x + 2) 3x − 2 = 5x + 10 8x = 8 x = 1
You have to distribute the 7 to x and 2 so : 7x+14=2x-1 Add one to both sides (inverse operations) 7x+14=2x-1 +1 +1 7x+15=2x Cross Cancel by subtracting 7x from both sides 7x+15=2x -7x -7x 15=-5x Divide by -5 15/-5= -5/-5 X= -3
