#t = 35/2#

Explanation:

To solve for the variable #t#, we need to make it by itself. The first step to do this is add #color(blue)13# to both sides:
#4t - 13 quadcolor(blue)(+quad13) = 57 quadcolor(blue)(+quad13)#

#4t = 70#

Now, divide both sides by #color(blue)4#:
#(4t)/color(blue)4 = 70/color(blue)4#

#t = 70/4#

Divide the numerator and denominator by #color(blue)2# to simplify:
#t = 70/4 quadcolor(blue)(-: quad2/2)#

Therefore,
#t = 35/2#

Hope this helps!
