I still don't get how to do this: Solve for t then simplify your answer. -6/5t=9

t= -15/2       or       t= -7.5

Step-by-step explanation:

We are given the equation:

and asked to solve for t. Therefore, we must isolate t on one side of the equation.

t is being multiplied by -6/5. The inverse of multiplication is division. We should divided both sides by -6/5, but we are dividing by a fraction. Instead, we can multiply by the reciprocal.

To find the reciprocal, flip the numerator (top number)  and denominator (bottom number).

-6/5 ----> -5/6

Multiply both sides of the equation by -5/6

Multiply across the numerator and denominator.

Simplify the fraction. Both the numerator and denominator can be divided by 3.

t is equal to -15/2 or -7.5

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
