are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}


3x plus 2y equals 20 and 5x-2y equals 1?

3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16


What are the order pairs for x plus y equals 8 and -x plus 2y equals 7?

x = 3 and y = 5


The addition method for x plus y equals 8 and -x plus 2y equals 7?

Add the two equations: x + y - x + 2y = 8 + 7 ie 3y = 15 so y = 5 making x = 3.


What is 7 plus 2y equals 15?

7+2y=15subtract 7 from each side of the equal sign2y=8divide each side by 2y=4


7 plus 2y equals 15?

Therefore, y = 4 7 + 2y = 15 7-7 + 2y = 15-7 Subtract 7 from both sides 2y = 8 Divide by 2 to get y alone 2y/2 = 8/2 y = 4

x = 8 and y = 0


What are ordered pairs for x plus 2y equals 8 and 2x plus y equals 7?

Rearrange the first equation: x=8-2y. Plug in this value of x into the second equation: 2(8-2y)+y=7. Simplify: 16-4y+y=7. -3y=-9. y=3. Plug this value of y into the first equation: x+2(3)=8. Solve for x: x=8-6. x=2. The answer is {2,3)


4x plus 2y equals -12 8x plus 6y equals -4?

3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8


8 plus 7 plus 5 equals plus 8 equals?

it is 28


What is the answer for 8 plus 2y equals 6?

8 + 2y = 6 Subtract 8 from both sides: 2y = -2 Divide both sides by 2: y = -1


Y intercept of 2y equals -6x plus 8?

2y = -6x + 8 The y intercept occurs when x = 0 2y = 8 therefore y = 4
