Answer:
t= -15/2 or t= -7.5
Step-by-step explanation:
We are given the equation:
[tex]\frac{-6}{5}t=9[/tex]
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
[tex]\frac{-5}{6} *\frac{-6}{5}t=9 *\frac{-5}{6}[/tex]
[tex]t=9 *\frac{-5}{6}[/tex]
[tex]t=\frac{9}1 *\frac{-5}{6}[/tex]
Multiply across the numerator and denominator.
[tex]t= \frac{9*-5}{1*6}[/tex]
[tex]t=\frac{-45}{6}[/tex]
Simplify the fraction. Both the numerator and denominator can be divided by 3.
[tex]t=\frac{-45/3}{6/3}[/tex]
[tex]t=\frac{-15}{2}[/tex]
[tex]t= -7.5[/tex]
t is equal to -15/2 or -7.5
