substitute x for y-1
2(y-1)-y=6 distribute
2y-2-y=6 subtract y in 2y
y-2=6 add 2 to get y by itself
y=8
Put y back into equation x=y-1
x=8-1
X=7
4x+6=14
4x=8
x=2
4x+6=-14
4x=-20
x=-5
Final answer: x=-5, x=2
Answer:
y=x+w/5
Step-by-step explanation:
x=5y-w
step 1: bring the additional letters/numbers next to the "5y" over to the left
x+w= 5y
step 2: divide the numbers and letters on both sides of the "=" by 5 to only get the letter y
x+w/5= y
step 3: swap them over
y= x+w/5
(we can't get an answer from x+w/5 because the terms are unlike, therefore we keep it as a fraction
78% = 78 / 100 = 0.78
What is 78% of 380
= 78% * 380
= 0.78 * 380
= 296.4
U said I should round it up IF NECESSARY so yeah....
