Answer:
This can be solved like this:
4x-3x+9=20
<em>Solving 4x-3x</em>
x+9=20
Transposing +9
x=20-9
And now we have, x=11
There is 100 centimeters in 1 meter.
Change the meter to centimeter. Multiply: 2 x 100 = 200
200 cm < 275 cm ∴ is greater by 75 cm
Add 3 to get a multiple of 7 with last digit 1. The only number in that range is 91, so our number is 88.
