Answer:

#t=-49#

Explanation:

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

# 7times(-7) = (t/-7)times-7#

then you can write:

#-49 = t#

It is your answer.

#t = -49#

When you divide t by -7, you will get

#-49/-7#

you get

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

I guess it explains everyting.

Answer:

See a solution process below:

Explanation:

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

#color(red)(-7) xx 7 = color(red)(-7) xx t/-7#

#-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#
