Question

Solve for the systems of equations.
2x+y=10
X=5
X
y

Answer 1

Answer:

Step-by-step explanation:

2x + y = 10

x = 5

2(5) + y = 10 ⇒ y = 0

Step-by-step explanation:

Step 1: Define systems

2x + y = 10

x = 5

Step 2: Solve for y

1. Substitute in x:                   2(5) + y = 10
2. Multiply:                              10 + y = 10
3. Isolate y:                              y = 0

And we have our final answer!
