4(0.5x + 2.5y - 0.7y - 1.3y + 4)
multiply 4 by all in parentheses
(4*0.5x)+(4*2.5y)+(4*-7y)+(4*-1.3y)+(4*4
=2x+10y-28y-5.2y+16
combine like terms
=2x-23.2y+16
ANSWER:
Expression simplified 2x-23.2y+16
Hope this helps! :)
Step-by-step explanation:
–(11/4) = 11 : (–4) = –11/4 = 11/-4
So one easy way is to make the equation equal to only one place holder so
-7x-4y=16
add 7x to both sdies
-4y=16+7x
multiply both sides by -1
4y=-16-7x
divide both sides by 4
y=-4-7/4x
subsitute values for x and get values for y
exg
if x=0 then y=-4
if x=1 then y=-5 3/7
etc
Answer:41
Step-by-step explanation:
