2(x - 2) + 3(x + 1) = 9
2x - 4 + 3x + 3 = 9 <em>distributed the 2 and 3 on the left side</em>
5x - 1 = 9 <em>added like terms (2x + 3x) and (-4 + 3)</em>
5x = 10 <em>added 1 to both sides</em>
x = 2 <em>divided 5 from both sides</em>
Answer: x = 2
Answer: 2 pies
Step-by-step explanation:
Here is the correct question:
There will be 6 people at Ellie's pie party. She wants to bake enough pie so that each person can eat at least 1/5 of a pie.What is the minimum number of pies Ellie should bake?
Since each person can eat at least 1/5 of the pie and there are 6 people, the 6 people would them eat at least (6 × 1/5) = 6/5 pie. Since we are talking about whole numbers with regards to the pie, it simply means that at least 2 pies should be baked.
<h3><u>Given</u> :</h3>
- 2x²y - 4xy², x = - 1 & y = 1
<h3><u>To Find</u><u> </u> :</h3>
<h3><u>Solution</u> :</h3>
2x²y - 4xy²
<u>Substituting the value of x & y</u>,
= 2(- 1)² × 1 - 4(- 1) × 1²
= 2 × 1 × 1 + 4 × 1
= 2 + 4
= 6
<u>Hence, The value of the expression is 6</u>.
