Answer:
none of these dude
Step-by-step explanation:
D - 10 - 2d + 7 = 8 - 10 - 3d
- d - 3 = - 2 - 3d
2d - 3 = - 2
2d = 1
d = 1/2
Hope this helps.
T = 4. first, you can add 2 to both sides of the equation. you get 4t = 16. then, you can divide both sides by 4 to isolate t.
Yeah so she spent half they year at the first one more than likely

Answer:
a. One solution
Step-by-step explanation:
These are two linear equations with different x-coefficients. They have one solution.

<em>Additional comment</em>
If the x-coefficients are the same, the system may have 0 or infinite solutions, depending on the constants. It is not possible for a system of linear equations to have exactly two solutions.
