Question

3 ( x - 1 ) + 2x = x +5

Answer 1

$\LARGE\tt{}3\left(x - 1\right) + 2x = x + 5 \\ \LARGE\tt{}3x - 3 + 2x = x + 5 \\ \LARGE\tt{}5x - 3 = x + 5 \\ \LARGE\tt{}5x - 3 - x = 5 \\ \LARGE\tt{}5x - x = 5 + 3 \\ \LARGE\tt{}4x = 5 + 3 \\ \LARGE\tt{}4x = 8 \\ \LARGE\tt{}x = \dfrac{8}{4} \\ \\ \LARGE\tt{}x = 2 \\ \\ \LARGE\tt{}s \{x = 2 \}$
