How do u solve (16-4÷2)2×3

84

Step-by-step explanation:

(16− 4 /2 )(2)(3)

=(16−2)(2)(3)

=(14)(2)(3)

=(28)(3)

=84

A) x = 3y+6
3y = x-6
divide both sides by 3.
y = (x/3) -2

b) x = 5y-10
5y = x+10
divide both sides by 5.
y = (x/5) +2

c) x = y^2
square root both sides.
y = sqrt(x)

d) x = 2y^2 -4
x+4 = 2y^2
divide both sides by 2.
(x/2) +2 = y^2
square root both sides.
y = sqrt((x/2)+2)

e) x = (y-5)^2
square root both sides.
sqrt(x) = y-5
y = sqrt(x) +5
