We want to determine if the ordered triple $\left(-9,-7,4\right)$(−9,−7,4) is a solution of the following system of equations.
$-2x$−2x | $+$+ | $5y$5y | $-$− | $3z$3z | $=$= | $-29$−29 |
$-3x$−3x | $+$+ | $y$y | $+$+ | $4z$4z | $=$= | $38$38 |
$-4x$−4x | $+$+ | $2y$2y | $+$+ | $3z$3z | $=$= | $34$34 |
Find the missing values by substituting in the ordered triple $\left(-9,-7,4\right)$(−9,−7,4).
