3x+y=-4
3x-4y=6

Solve the simultaneous equation

Good morning ☕️

Step-by-step explanation:

3x+y=-4   (1)

3x-4y=6  (2)

solving by elimination:

(1) - (2) ⇒

3x + y  = -4

3x - 4y = 6

________

0 + 5y  = -10

5y = -10 ⇔ y = -2

(2) ⇒ 3x-4y=6  ⇒ 3x-4(-2)=6  ⇒ 3x = 6 - 8 = -2 ⇒ x = -2/3

:)

x = 2, y = -2

Step-by-step explanation:

Subtract the two equations:

3x+y=-4equation 1

3x-4y=6equation 2

5y = -10

Divide both sides by 5 to get the value of y

y = -2

Insert the value of y into equation 1 to get the value of x

3x + y = -4

3x + (-2) = -4

3x -2 = 4

3x = 4 +2

3x = 6

Divide both sides by 3 to get the value of x

x = 6/3

x = 2

Check: insert the values of x and y into equation 1

3x + y = 4

3 (2) + (-2) = 4

6 - 2= 4

I hope this is clear, please mark as brainliest answer.

correct

step-by-step explanation:

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
