(7/10)*x= 1400
0.7*x = 1400
x = 1400/0.7 (divide both sides by 0.7)
x = 2000
or
(7/10)*x= 1400
x = (1400/1) / (7/10) {divide both side by 7/10}
x= (1400/1) * (10/7) {keep change flip}
x = 14000/7
x= 2000

(7/10)*x = 1400
This can be written as:
7x/10 = 1400
7x = 1400*10 (Multiply both sides by 10)
7x = 14000
x = 14000/7 (Divide both sides by 7)
x = 2000

you have 7/10x=1400 so then you multiply both sides by 10/7 and you should be left with x= then your answer. Cuz I'm not donig your homework for you. <3

Take:
7/10 times x/1 = 1400
Multiply the numerators:
7x/10 = 1400
To get 7x by itself, multiply by 10 on both sides
Leaves 7x = 14000
Solve for x by dividing both sides by 7

oh simple..
(7/10)^x=1400
means
xlog(7/10)=log1400
x=(log1400)/(log(7/10))
