2(1) + y = 4

2 + y = 4

y = 2

Solve the equations using the substitution method:<br> 4x -2y =22<br> 2x + 4y = 6
Ugo [173]
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
