Answer:
x = 1 and y = −2
Step-by-step explanation:
Rewrite equations:
x + 2y = −3
3x − 2y = 7
Step 1: Solve x+2y=−3 for x:
x + 2y = −3
x + 2y + −2y = −3 + −2y (Add -2y to both sides)
x = −2y − 3
Step 2: Substitute −2y − 3 for x in 3x − 2y = 7:
3x − 2y = 7
3(−2y − 3) − 2y = 7
−8y − 9 = 7 (Simplify both sides of the equation)
−8y − 9 + 9 = 7 + 9 (Add 9 to both sides)
−8y = 16
−8y/−8 = 16/−8 (Divide both sides by -8)
y = −2
Step 3: Substitute −2 for y in x = −2y − 3:
x = −2y − 3
x = (−2)(−2) − 3
x = 1 (Simplify both sides of the equation)

Reteach the (x,y) coordinate structure and axes to the whole class.
When the majority of the class does not understand a topic, it should be retaught in a different manner.
A coordinate plane is a dimensional plane fashioned by way of the intersection of a vertical line known as the y-axis and a horizontal line known as the x-axis. These are perpendicular traces that intersect each differently at zero, and this point is called the origin.
Here are the characteristics for each of the four coordinate plane quadrants:
- Quadrant I: positive x and positive y.
- Quadrant II: negative x and positive y.
- Quadrant III: negative x and negative y.
- Quadrant IV: positive x and negative y.
The XY Coordinate plane is fashioned while two quantity strains (called axes) meet at a 90° attitude. The horizontal line is called the x-axis and the vertical line is known as the y-axis. The point where they meet is referred to as the beginning. The axes separate the plane into four sections called quadrants.
