t=-49t=49

Explanation:

You can arrange your equation (by multiplying both sides with -7):

7times(-7) = (t/-7)times-77×(7)=(t7)×7

then you can write:

-49 = t49=t

It is your answer.

t = -49t=49

When you divide t by -7, you will get

-49/-7497

you get

=(-7times7)/-7 = 7=7×77=7 which is equal to the first term (7) in your original equation.

I guess it explains everyting.

See a solution process below:

Explanation:

Multiply each side of the equation by color(red)(-7)7 to solve for tt while keeping the equation balanced:

color(red)(-7) xx 7 = color(red)(-7) xx t/-77×7=7×t7

-49 = cancel(color(red)(-7)) xx t/color(red)(cancel(color(black)(-7)))

-49 = t

t = -49

To check the solution we need to substitute -49 for t in the original equation and calculate the right side of the equation:

7 = t/-7 becomes:

7 = (-49)/-7

7 = 7
