4x - 2y = 14
y = 0.5x -1
Get just one variable on one side for both equations.
4x - 2y = 14 ⇒ 4x = 2y + 14 ⇒ 4x - 14 = 2y
y = 0.5x - 1 ⇒ x - 2 = 2y
Use the transitive property and then solve for x.
x-2 = 4x-14
12 = 3x
x = 4

Step-by-step explanation:

Answer:
x = -5.39
Step-by-step explanation:

x = -5.39
Answer:
2, 16, 14 in orders from top.
Step-by-step explanation:
a/4=1/2 4 x 0.5 = 2
3/b=1/2 3 x 2 = 6
5/10=1/2
