Answer:
.
Step-by-step explanation:
Hey there!
ORIGINAL EQUATION:
1/2y + 1 = 2
SUBTRACT 1 to BOTH SIDES:
1/2y + 1 - 1 = 2 - 1
CANCEL OUT: 1 - 1 because it give you 0
KEEP: 2 - 1 because it help solve for the y-value
NEW EQUATION: 1/2y = 2 - 1
SIMPLIFY IT!
1/2y = 1
MULTIPLY 2 to BOTH SIDES
1/2y * 2 = 1 * 2
CANCEL out: 1/2 * 2 because it give you 1
KEEP: 1 * 2 because it give you the y-value
NEW EQUATION: y = 2 * 1
SIMPLIFY IT!
y = 2
Therefore, your answer is: y = 2
Good luck on your assignment & enjoy your day!

For the blue picture, use Pythagorean theorem. So 8.7^2 + x^2 = 32^2. Now solve for x and that’ll give you the missing side
-x+5y=20
5y=x+20
12y=2x+60
6y=x+40
x+20+y=x+40
-x from each side:
20+y=40
-20 from each side:
y=20
-x+5*20=20
-x+100=20
-100 from each side:
-x=-80
x=80
y=20
x=80
Hope this helps :)
