y = 2x +10
y = -2x - 6
Since both equations are equal to y, we can equate them to each other:
2x + 10 = -2x - 6
Now, just use algebra to solve for x by isolating it to one side of the equal sign.
2x +10 + 2x = - 6
4x +10 = - 6
4x = - 6 - 10
4x = -16
x = -16/4
x= -4
Now substitute this x = -4 into any of the initial two equations. Let us use the 1st equation:
y= 2x + 10
y= 2*(-4) + 10
y= -8 +10
y = 2
So now we solved it: x =-4 , y = 2
