Answer:
z = 92
Step-by-step explanation:
9 (z - 82) = 90
Divide both sides by 9
z - 82 = 90/9
z - 82 = 10
add 82 to both the sides,
z - 82 +82 = 10 +82
Z=92
Distribute, 9z-738=90
Add 738, 9z=828
Divide, z=92
2x2 + x - 10
d=-4
20 = –d + 16
Subtract 16 from each side
20-16 = –d + 16-16
4 = -d
Multiply each side by -1
-1 *4 = -1 * -d
-4 =d
