Question

Solve the equation 3x-2y =7, x+2y= -3​

Answer 1

Answer:

x = 1

y = -2

Step-by-step explanation:

adding both quation we get

3x -2y + x + 2y =7 + -3

4x = 4

x = 1

substituting this equation in the earlier equation we get

3 * 1 -2y = 7

3 - 2y = 7

-2y = 4

y = -2

Answer 2

Answer:

• x=1
• y= -2

Step-by-step explanation:

• 3x-2y =7
• x+2y= -3
• 4x=4
• x=4/4
• x=1
• 3x-2y=7
• 3(1)-2y=7
• 3-2y=7
• -2y=7-3
• -2y=4
• 2y=-4
• y=-4/2
• y= -2
• Verify solution
• x+2y= -3
• 1+2y= -3
• 2y=-3-1
• 2y= -4
• y= -4/2
• y= -2
