Answer:
Step-by-step explanation:
2 + (-3) + 7 = 2 - 3 + 7 = 9 - 3 = 6 <==
a positive multiplied by a negative will be negative
2x4=8
8+3=11
11/4
I hope this helped
The next one would be that teal color (circle) and then the square would be purple
2x-9=-x+6
+x +x
3x-9=6
+9 +9
3x=15
x=5
therefore the equations have one solution (x=5)
