Question

x+3=-25, -3x+15=-27, 11x-33=5x-8, 1(x+7)-8=56​

Answer 1

Explicație pas cu pas:

x+3=-25

x=-25-3

x=-28

-3x+15=-27 (scadem din ambele parti 15)

-3x=-27-15

-3x=-42

x=-42÷-3(minus ÷ minus = plus)

x=14

11x-33=5x-8 (adunam in ambele parti 8)

11x-33+8=5x-8+8

11x-25=5x

25+5x=11x (scadem 5x din ambele parti)

25+5x-5x=11x-5x

25=6x

x=25÷6

x=4,1(6)

x+7-8=56

x+7=56+8

x+7=64

x=64-7

x=57
