Calculation:
a. Inequality is 4<2y or 3(y+2)2y+1
Solution is given as:
4<2y or 3y62y+1
y>2 or 3y+2y>6+1
y>2 or y>7
y>2 or y<7
Solution in interval notation form is 8,7?(2,8)
b. Inequality is 4<2y and 3(y+2)2y+1
Solution is given as:
4<2y and 3y62y+1
y>2 and 3y+2y>6+1
y>2 and y>7
y>2 and y<7
Solution in interval notation form is 8,7n(2,8)
Conclusion: Hence, the solutions for the below equations and inequalities are as follows:
a. 4<2y or 3(y+2)2y+1:

Solution is y<7 or y>2
b. 4<2y and 3(y+2)2y+1:

Solution is y7 and y>2
