Answer:
you have it right its 29 and 5
Step-by-step explanation:
[7×(-3)] × (-2)²
= (-21) × 4
= -84
<span>simplify third eqn -2x+5y+2x=4
5y=4
y=4/5
substitute back to 1st n 2nd eqn n solve for x n z
-4x-4-z=18 and -2x-4-2z=12
simplify -4x-z=22 and -2x-2z=16
-4x-(-x-8)=22
-3x+8=22
x=-14/3
z=-10/3
y=4/5
