77 is the answer i believe i hope i helped
To solve divide both sides by 4 to cancel out the 4 on the x side to get x alone. Then just do -10/4. That gives you 2.5 so (X=2.5). Hope I helped and have a great day and night
X = 6, y = 8, z = 3
3(8) + (6)² = 24 + 36 = 60
= 20
She would pay $85.10 in total
74(.15)= 11.1
74+11.1= 85.10
