The given inequalities are :
2x + 8 > 18
2c + 8 < 18
Inequality 1 : 2x + 8 > 18
Simplify
Subtract 8 from both side :
2x + 8 - 8> 18 - 8
2x > 10
Divide both side by 2
x > 5
Inequality : 2c + 8 < 18
2c + 8 < 18
Subtract 8 from both side:
2c + 8 - 8 < 18 - 8
2c < 10
Divide both side by 2:
2c/2 < 10/2
c < 5
So, the solution is x > 5 and c < 5
So, equation will be : c < x < 5
