Answer 1

Answer:

x = 4

Explanation below.

Step-by-step explanation:

First, let's solve the system of equations.

Since both equations have y equal to something, we'll substitute one y - value for the other given that,

y = 0.5x + 1

y = -x + 7

So substitute:

-x + 7 = 0.5x + 1

Solve for x:

-1.5x + 7 = 1

-1.5x = -6

x = 4

When we solve this system of equations, we get the solution x = 4.

Answer 2

Answer:

Yes

Explanation:

Given two equations:

1. y = 0.5x + 1
2. y = -x + 7

Solve:

0.5x + 1 = -x + 7

0.5x + x = 7 - 1

1.5x = 6

x = 6/1.5 = 4

y = -x + 7 = -(4) + 7 = 3

Solution: (4,3)
