Bien sûr, je vais résoudre ces équations pour toi :

a) \(2x + 7 = 28\)
\(2x = 28 - 7\)
\(2x = 21\)
\(x = \frac{21}{2}\)

b) \(3x + 5 = 5x + 8\)
\(3x - 5x = 8 - 5\)
\(-2x = 3\)
\(x = -\frac{3}{2}\)

c) \(2(x + 3) = 4(2-1)\)
\(2x + 6 = 4\)
\(2x = 4 - 6\)
\(2x = -2\)
\(x = -1\)

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