Answer:
Step-by-step explanation:
you need to show the answers
Y = -7
x = -19
Steps:
Add the two equations together:
y - x + y + x = -14
2y = -14
y = -7
-7 + x = -26
x = -19
Answer:
4?
Step-by-step explanation:
You could draw a square, rectangle, parallelogram, and other shapes that make four sides or more.
Assuming that the equations are (x+7) and (3x-8) because the first equation does not have a sign these are the steps. When you multiply you will get 3x^2+21x-8x-56. After this you will simplify and you will get your final answer which is 3x^2+13x-56. Also if I used the wrong equations please let me know and I can help you with the correct ones.
