Question

2x+12=30
explain steps

Answer 1

Answer: x=9

Explanation:

2x+12=30

you must isolate x, that is, leave it aside, still:

2x=30-12

12 started to subtract, because whenever a number passes to the other side it reverses the sign, if it is adding, it subtracts, and if it is multiplying, it divides

2x=18

x=18/2

we just want to find the value of x, and as we said last time, the 2 is multiplying by x, and when it goes to the other side, it will be dividing by 18

x=9

Answer 2

ANSWER IS 9

Steps-

2x +12=30

Move 12 to the right side
2x=18

Divide both sides by 2
X = 9
