- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x + 4y = -8
-5x - 4y = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -6x = -24
- Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -x + 4y = -8
- Substitute in <em>x</em>: -4 + 4y = -8
- Isolate <em>y</em> term: 4y = -4
- Isolate <em>y</em>: y = -1
For this kind of problems, first find the method to solve, then face the fractions.
If I jog 100 miles in a year, and I do 2 miles a day. How many days did I jog?
We know easily that it is 100 days/ 2 miles/day = 50 days.
So the number of days is total distance / how much a day, or
(6 1/2) divided by (1/6)
The exact form is x= -3/14
3 ways because 12 divided by 4 is 3.
