6(x + 8) = 48
6 left parenthesis x plus 8 right parenthesis equals 48
8(x − 6) = 48
8 left parenthesis x minus 6 right parenthesis equals 48
6x − 8 = 48
6 x minus 8 equals 48
6(x − 8) = 48
8(x − 6) = 48

10(x + 2) = 16
10 Left Parenthesis x plus 2 Right Parenthesis equals 16
2(x + 10) = 16
2 Left Parenthesis x plus 10 Right Parenthesis equals 16
2x + 10 = 16
2 x plus 10 equals 16
2(x − 10) = 16
2x + 10 = 16
