21 (x - 1) + x = 100 - 2 (x - 1)

21x - 21 + x = 100 - 2x + 2

22x -21 = 102 - 2x

22x + 2x = 102 + 21

24x = 123

x = 123/24

X = 41/8

5x + 5 (x - 3) = 15
Weegy: x=3 (which would make it 15 + 0 = 15) User: x + 3 (x - 4) = 2 (x - 2) - 20 Weegy: ((3 / 5) * 0.6) - ((2 / 3) * 0.15) = 0.26 Thanks for asking Weegy. User: 10 - 5 (x - 5) = 4 (x - 1) User: The sale price of a suit is three-fifths of the original price. Let p denote the original price of the suit.

5x + 5 (x - 3) = 15;
5x + 5x - 15 = 15;
10x = 15 + 15;
10x = 30;
x = 30/10;
x = 3

x + 3 (x - 4) = 2 (x - 2) - 20;
x + 3x - 12 = 2x - 4 - 20;
4x - 12 = 2x - 24;
4x - 2x = -24 + 12;
2x = -12;
x = -12/2;
x = -6

10 - 5 (x - 5) = 4 (x - 1);
10 - 5x + 25 = 4x - 4;
-5x + 35 = 4x - 4;
-5x - 4x = -4 - 35;
-9x = -39;
