- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 4
y = -x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 4 = -x + 5
- Add <em>x</em> to both sides: 3x - 4 = 5
- Add 4 to both sides: 3x = 9
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -x + 5
- Substitute in <em>x</em>: y = -3 + 5
- Add: y = 2
Answer:
It will take 9 cups of sugar to make 12 pies.
Step-by-step explanation:
If it takes 6 cups of sugar to make 8 pies, than we can calculate that takes 0.75 cups of sugar to make 1 pie. We can use this to calculate that 12x0.75=9, which means that it takes 9 cups of sugar to make 12 pies.

Answer: x - 16
Step-by-step explanation:
Since there were x cupcakes at the beginning of a party and at the end of the party, 16 of them had been eaten, the expression for the number of cupcakes that were left will be gotten by subtracting the number of cupcake that have been eaten from the cupcakes at the beginning. This will be:
= x - 16
For example, if there were 20 cupcakes at the beginning and 16 was eaten, the number left will be:
= x - 16
= 20 - 16.
= 4
There'll be 4 left
