Answer:
a
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:

Answer:
2(3x+y=4)
1(x+2y=-2)
6x+2y=8
<u>(-) x+2y=-2</u>
<u>5x=10</u>
5
x=2
x+2y=-1
2+2y=-1
<u>-</u><u>2</u><u> -</u><u>2</u>
<u>2y=-</u><u>3</u>
2
y=-3/2
Step-by-step explanation:
- multiply the first equation by 2 to make y equal to each other.
- subtract to eliminate y
- divide by 5 to get x
- take one of the equations
- replace x by 2 to solve for y
Answer:
y = 3

Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
Point (3, 3)
Slope<em> m</em> = 0
<u>Step 2: Find</u>
<em>When the slope is equal to 0, you will have an equation of a horizontal line at a y-coordinate point.</em>
y-coordinate: 3
Equation: y = 3
