To solve the equation $2.1(x+4.9)-4.1=3(x+4)-5$, first distribute the numbers outside the parentheses:$$2.1x + 10.29 - 4.1 = 3x + 12 - 5$$Simplify both sides:$$2.1x + 6.19 = 3x + 7$$Subtract $2.1x$ and $7$ from both sides to get the x terms on one side and the constants on the other:$$6.19 - 7 = 3x - 2.1x$$Simplify:$$-0.81 = 0.9x$$Divide both sides by $0.9$:$$x = -0.9$$So, the correct answer is $x = -0.9$, which corresponds to choice C.
