Question

Use algebraic rules of equations to predict the solution type to the system of equations. Include all of your work for full credit. $\left \{ {x+y=-4} \atop {y=2x-1}} \right.$

Answer 1

Answer:

x = -1 and y = -3

Step-by-step explanation:

x+y = -4 ------> 1

y = 2x-1 ------> 2

substitute y from equation 1 in equation 1

x+2x-1=-4

3x = -3

x=-1

substitue this x in equation 1

-1 +y =-4

y = -3
