Isolate x in 2nd equation...
-x - 2y = -10 ....add 2y to both sides
-x = 2y - 10 ...multiply by -1 to make x positive
x = -2y + 10 <== u would sub in -2y + 10 in for x in the 1st equation
9 x (400 + 75)
3 (3) x 100 (4.75)
For example:
20,484,163 in expanded form
2 ten million and 0 one million and 4 hundred thousand and 8 ten thousand and 4 one thousand and 1 hundreds and 6 tens and 3 ones.
or
<span>2 x 10,000,000 + 0 x 1,000,000 + 4 x 100,000 + 8 x 10,000 + 4 x 1,000 + 1 x 100 + 6 x 10 + 3 x 1</span>
