Question

3. (x - 1) + 8 = 2(x + 4) - 8

Answer 1

$\LARGE\tt{}3(x - 1) + 8 = 2(x + 4) - 8 \\\LARGE\tt{}3x - 3 + 8 = 2(x + 4) - 8 \\ \LARGE\tt{}3x - 3 + 8 = 2x + 8 - 8 \\\LARGE\tt{}3x - 3 \: \cancel{ + 8} = 2x \: \cancel{ + 8} - 8 \\ \LARGE\tt{}3x - 3 = 2x - 8 \\ \LARGE\tt{}3x - 3 - 2x = - 8 \\ \LARGE\tt{}3x - 2x = - 8 + 3 \\ \LARGE\tt{}x = - 8 + 3 \\ \LARGE\tt{}x = - 5 \\ \\ \LARGE\tt{}s: \{ - 5 \}$
