Solve the system
<span>y = x + 4
y = 3x + 6
Note that both equations have been solved for y. Thus, you can set y = y, or
x+4=3x+6. Simplifying, -2 = 2x, or x = -1.
Another way to look at this would be x + 4 = 3x + 6.</span>
42300 / 10 = 4230
4230 * 500 = 2115000
a number multiplied by ten equals to 42300, so 10a = 42300, then a = 4230, then you multiply 4230 and 500 together, which gives you 2115000
