Answer:
t=4
Step-by-step explanation:
Use the distributive property first on the left side (multiply 2 by t and 2 by 1). This leaves you with 2t+2=10. Then you just have a multistep equation. Subtract 2 from both sides (2 cancels out on the left side and you are left with 8 on the right side). Equation now looks like 2t=8. Then, you divide by 2 on both sides to isolate the t and you get 4.
