Potrzebuje 5 rozwiązanych równań liniowych !
Można wstawić zdjęcie ja sobie odpisze ( żeby dało się rozczytać ) !
1.
2(x + 3) = 18 2x + 6 = 18 2x = 18 - 6 2x = 12 x = 6 2.
x + 3(x - 2) = -22 x + 3x - 6 = -22 4x = -22 + 6 4x = -16 x = -4 3.
5x -2(x + 3) = 9 5x - 2x - 6 = 9 3x = 9 + 6 3x = 15 x = 5 4.
4(2x +3) - 5x = -3 8x + 12 - 5x = -3 3x = -3 - 12 3x = -15 x = -5
5.
2(x + 1) + 5x = 16 2x + 2 + 5x = 16 7x = 16 - 2 7x = 14 x = 2

2x = 18 - 6
2x = 12
x = 6
2.
x + 3(x - 2) = -22
x + 3x - 6 = -22
4x = -22 + 6
4x = -16
x = -4
3.
5x -2(x + 3) = 9
5x - 2x - 6 = 9
3x = 9 + 6
3x = 15
x = 5
4.
4(2x +3) - 5x = -3
8x + 12 - 5x = -3
3x = -3 - 12
3x = -15
x = -5
5.
2(x + 1) + 5x = 16
