see the explanation
Step-by-step explanation:
Let
x -----> the number
we know that
Three-eighths multiplied by a number plus one must be equal to 11
so
The linear equation that represent this situation is
Solve for x
Subtract 1 both sides
Multiply by 8/3 both sides
The number is 80/3
(5+7(x^3)+3(x^2)) + (-12+5x+6(c^2))
-7 + 7x³ + 3x² + 5x + 6c²
