For which equation is x=5 a solution? Help me please ty :) A.2+x=3 C. x/2=10
B.3x=15 D. x-7=12

B)3x=15

Step-by-step explanation:

3x=15

x=15/3

x=5 (proven)

-4

step-by-step explanation:

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

=
