Distribute the 5:
5 + 10t - 4 = 8t
Combine like terms:
1 = -2t
Divide both sides by -2:
t = -1/2

First multiply through the parentheses:

5 + 10t - 4 = 8t

Now, combine like terms:

1 + 2t = 0

2t = -1

t = -1/2

5 + 10t - 4 = 8t
10t +1 = 8t
1=8t - 10t
1 = -2
1/-2 = t

Ok, let's see,

5(1+2t) - 4 = 8t
5 + 10t - 4 - 8t= 0
2t + 1 = 0

2t = -1
t = -1/2

Good luck!

5 (1+2t)-4 = 5 x (3t)-4
15t-4=11t

5 +10t-4=8t
1=8t-10t
1=-2t

t= -!/2
t=0.5
