solve the equation 2.50+1.25x=22

Question

the euqation is to be solve

Answer 1

2.50 + 1.25x = 22  first we must get x by itself, to do this we first subtract 2.50. (what you do to one side you have to do to both sides)

2.50-2.50 +1.25x = 22-2.50

1.25x = 19.5   now you see x is being multiplied by 1.25 so to undo this you have to divide it by 1.25 and what you do to one side you have to do to the other

1.25x/1.25 = 19.5/1.25     

1x = 15.6

x= 15.6
