L'exercice n38 svp ctrop urgent sauver moi svvppp !!

Bonsoir,

[tex]1)\ -3(x+5)=1-2(x+1)\\-3x-15=1-2x-2\\-3x+2x=1-2+15\\-x=14\\\boxed{x=-14}\\\\2)\ x-(7x-2)=5(2-x)\\x-7x+2=10-5x\\x-7x+5x=10-2\\-x=8\\\boxed{x=-8}[/tex]

[tex]3)\ 1-(5-2x)=3-(2x-5)\\1-5+2x=3-2x+5\\2x+2x=3+5-1+5\\4x=12\\\\x=\dfrac{12}{4}\\\\\boxed{x=3}[/tex]

[tex]d)\ 5x-(2x-5)=1-3(2-x)\\5x-2x+5=1-6+3x\\5x-2x-3x=1-6-5\\0x=-10\\\\\boxed{Equation\ imposssible}[/tex]
