Answer:
★ = 3
✚ = 4
■ = 4
◆ = 5
Step-by-step explanation:
If we use direct correspondence in the second equation, then we have ...
◆ = 5
★ = 3
The values of ★ and ✚ in the first equation must total 7. This means ...
✚ = 7 -3 = 4
Again, using direct correspondence in the third equation, we have ...
■ = 4
