$1\mathrm{.}25J_1-0\mathrm{.}0475J_2-0\mathrm{.}2025J_3=16226\mathrm{.}48$

$-0\mathrm{.}3166J_1+1\mathrm{.}666T_2-0\mathrm{.}635J_3=1099\mathrm{.}47$

$-0\mathrm{.}0675J_1-0\mathrm{.}3176J_2+0\mathrm{.}3831J_3=0$

$]$ can someone help show and explain how these simultaneosu equations are solved to obtain J thank you
