Calculate $H$ for this reaction

$C_4{H}_8+6O_{2}4C{O}_2+4H_{2}O$

using the thermochemical equations below.

$C_4{H}_8+H_2{C}_4{H}_{10},H_1=-126kJ$

$2C_4{H}_{10}+13O_{2}8C{O}_2+10H_{2}O,H_2=-5754kJ$

$H_2+\frac{1}{2}{O}_2{H}_{2}O,H_3=-286kJ$

$H=kJ$

Enter either $a+$ or $-$ sign and the magnitude. The last answer i tried $(-5970$ and $+5970)$ were both incorrect.
