Expressions cannot <u>be solved.
</u>Although they are similar to equations, you can solve an equation, but you cannot solve an expression. You can evaluate it, simplify it, and it can have many variables, however, an expression just exists, it is not a problem that has to be solved.<u>
</u>
3(-x - 4) = 3x + 5(x + 2)
x=-2
V that is potential diff is equal to current multiplied by resistance. This snows that v is proportional to current directly
First find highest common factor of 12 and 84=12
12(t-7)
