Answer
y = 2x +8
Step-by-step explanation:
Add 2
x to both sides of the first equation to get:
y
=
8
+
2
x
Divide both sides of the second equation by 2 to get:
y
=
8
+
2
x
The two equations determine the same conditions on xy so this system of equations has an infinite number of solutions, namely all points on the line:
y
=
2
x
+
8
Step-by-step explanation:
<u>The standard form of linear equation:</u>
<u>Convert each equation into standard form:</u>
<h3>#5</h3>
- 3x = 18
- 3x + 0y - 18 = 0
- A = 3, B = 0, C = - 18
<h3>#6</h3>
- y/2 = - 5
- 0x + 1/2y + 5 = 0
- A = 0, B = 1/2, C = 5
Answer: -23
Step-by-step explanation:
-5-2x-2y
-5-2(3)-2(6)
-5-6-12 = -23
