Question

Solve the the equations (1) 9x + 2=20​

Answer 1

Answer:

x = 2

Step-by-step explanation:

Given,

9x + 2 = 20

9x = 20 - 2

x = 18 ÷ 9

x = 2

Answer 2

Answer:

Firstly you need to eliminate the +2 at the left hand side (LHS) and bring it over to the right hand side (RHS). Doing this you'll need to change the +2 to -2. this is then will be

9x=20-2

continue by solving the equation at the (RHS)

which will be

9x=18

then to only leave the unknown on the (LHS) you'll need to bring the 9 to the (RHS)

in this case its 9x which means 9*x. so 9 will not be a -9 on the (RHS) but will be a /9 which is divide by 9. you dont need to change the + sign on the 9.

that leaves

x=18/9

x=2.
