Solve the following system of equations.
-2x + y = 10
4x - y = -14

Step-by-step explanation:

Solution by substitution method

-2x+y=10

2x-y=-10

and 4x-y=-14

Suppose,

2x-y=-10→(1)

and 4x-y=-14→(2)

Taking equation (1), we have

2x-y=-10

⇒y=2x+10→(3)

Putting y=2x+10 in equation (2), we get

4x-y=-14

4x-1(2x+10)=-14

⇒4x-2x-10=-14

⇒2x-10=-14

⇒2x=-14+10

⇒2x=-4

⇒x=-2→(4)

Now, Putting x=-2 in equation (3), we get

y=2x+10

⇒y=2(-2)+10

⇒y=-4+10

⇒y=6

∴y=6andx=-2

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 : )
