This one u probably have to choose more than one

Replace with 27, solve for , and see if the result is a whole number.

27 = 2a   ⇒ = a not a whole number  NO

27 = 2a + 1  ⇒  26 = 2a  ⇒  13 = a  13 is a whole number  YES

27 = 3a  ⇒  9 = a   9 is a whole number  YES

27 = 3a + 6   ⇒   21 = 3a   ⇒   7 = a   7 is a whole number  YES

27 = 3a + 1   ⇒   26 = 3a   ⇒   = a not a whole number  NO

B, C, D

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
