Question

Va rog ajutati-ma ! Este urgent ! Multumesc !

Answer 1

a)

$5(x+2)-4x+3=-3(x+1) \\5x+10-4x+3=-3x-3 \\x + 13 = -3x-3 \\4x = -16 \\x = -4$

b)

$4-(-3)[(-11)x+(-13)*(7)]:(-18) = 10 \\ 4+3(-11x-91):(-18) = 10 \\ 3(-11x-91):(-18) = 6 \\ 3(-11x-91) = -108 \\-11x-91 = -36 \\-11x = 55 \\x = -5$

c)

[tex] 7x-3(x+1)=2x+15 \\7x-3x-3=2x+15 \\4x-3=2x+15 \\2x=18 \\x=9[/tex]

d)

[tex]2*[5(x+2)+9]=68 \\2*(5x+10+9)=68 \\5x+19=34 \\5x = 15 \\x = 3[/tex]

e)

[tex]47-5(x+2)=3(x+5)-10 \\47-5x-10=3x+15-10 \\-5x+37=3x+5 \\-2x=-32 \\x=16[/tex]
