Question

Can someone Plzzz help me

Answer 1

So for the first question, you basically add up all of the sides. So it would be 3y+5+3y+1+2y+6+2y+3y-4+2y+2y+8+4y-2

To simplify that combine like terms so 17y+14

For the second part of the question, it's easy algebra.

Here's your problem 17y+14=77

To solve that get the variable by itself, subtract the constant, 14, from both sides.

17y+14 -14=77 -14

17y=63

Now divide each side by the coefficient, 17

y=3.71

I might be wrong in my math somewhere, but the method is the same... you might want to check it to make sure.
