Question 733650
to solve any type of equation with an unknown on both sides of the equals sign....
look for the side with the least unknowns
so 8x+2=5x+23
the right hand side (of the equals sign) has 5x and the left hand side has 8x.
so we take 5x from both sides to eliminate the +5x from the right hand side
giving
8x+2-5x=5x+23-5x
simplifying gives
3x+2=23
Now we have to eliminate the number from the side with the unknown on
So we have to subtract 2 from both sides to get rid of the +2 from the right hand side
giving
3x+2-2=23-2
simplifying gives
3x=21
Dividing both sides by 3 gives us
x=7
