I’m not 100 percent sure someone can comment on this and confirm but when it’s written like a fraction it means division. If they gave you the meaning of each variable (the letters) multiply each variable by each coefficient (the number next to the variable). Multiply all of those. Then divide it by the product of 4 and the variable
Hope this helped!
I believe that answer is 31
3/5t -4 -7/10t = -2 (as you know 3/5 = 6/10) so
6/10t - 4 - 7/10t = -2
Simplify
-1/10t -4 = -2
add 4 to both sides
-1/10t - 4 + 4 = -2 + 4
-1/10t = 2
multiply -10 to both sides
-1/10t *(-10) = 2 * (-10)
Simplify
t = -20
Answer first one t = -20
