{y=2x+7y=−4x−5 what is the solution for the system of equations?

Since both start with y, we can set them equal to each other. 2x+7 = -4x - 5.  This means we add 4x to both sides, 6x + 7 = -5. Then we subtract 7 from both sides, 6x = -12. Finally we divide both sides by 6, and x = -2.

Hey there,   128 *(2/3) = 85.3

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams
