4d+6+2d can be reduced to 6d+6
This can also be rewritten as 6(d+1).
Solve simultaneously:
<span>15x-8y=52 and
6x+14y=38
</span>
Let's solve this system thru elimination by addition/subtraction:
Let's get rid of the x terms.
To do this, mult. the first eqn. by -6 and the second by 15. (This is not the only way in which we can do this!!) We get
-90x + 48y = -312
90x +210y = 570
--------------------------
Add all 3 columns together. We end up with:
258y = 258, so y = 1. You can find x by subst. 1 for y in either of the given equations.
If you'd like more help, please be specific about what you want.
you have to convert meters to centi-meters first;
800m = 80000 cm & 154m = 15400 cm
Now, Substitute that in your original equation;
80035 cm - 15449
64586 cm
The answer is because of the 4 outcomes and 2 different outcomes of each.
