We have that
<span>4x -2y =22------> clear variable y
2y=4x-22--------> y=4x/2-22/2---------> y=2x-11-----> equation 1
2x + 4y = 6------> equation 2
substitute equation 1 in equation 2
2x+4*[2x-11]=6-----> 2x+8x-44=6----> 10x=50------> x=5
then
y=2x-11----> y=2*5-11----> y=-1

Answer:
option 2
Step-by-step explanation:
Substitute x = - 5 into f(x) , that is
f(- 5) = 4(- 5) - 7 = - 20 - 7 = - 27
Both x and y equal 2.
2•2=4 + 2•2=4
4+4=8
2+2=4

Answer:
(-1, -9)
Step-by-step explanation:
Recall that for 2 points (x1, y1) and (x2,y2)
the midpoints are given by
x ordinate =
y ordinate = 
In our case x1 = 8, y1 = -10, x2 = -10, y2=-8
x ordinate =
= [8 + (-10) ] / 2 = -1
y ordinate =
= [-10 + (-8) ] / 2 = -9
hence midpoint is (-1, -9)
