Given the equation.

5t + 5 = 5t -4

This equation has NO solution because when you subtract 5t from both sides you get 5 = -4

Then both sides can not be equation for any value of t.

`==gt t= phi.`

5t + 5 = 5t - 4

To solve equation like this , you would have to move the " x "  to the same side of the equation. In order to get " x " on the same side of the equation you would have to subtract 5t on both sides

By subtracting, your equation should look like

5 = 4 because since 5 does not equal to 4

your answer is no solution

There is no solution because if you subtract 5t from each sides then it says 5=-4 which is not true

this equation has no solution because if you try to isolate the unknown variable, you end up eliminating the unknown variable completely.

5t + 5 = 5t - 4

Try isolating variables and combining like terms and you'll find that you'll end up with a nonsensical statement such as 0 = 1. This clues us in on the fact that this particular problem has no solution.

`5t+5=5t-4`

combine like terms

`5t-5t=5-4`

`0t!=1`

so it is either 0 or no solution

5t + 5= 5t - 4

Squaring Both Sides

25t2 + 50t + 25 = 25t2 – 40t + 16

50t + 40t = 16 – 25

90t = -9

t = - (9/90)

t = -1/10
