<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of black tea worth 1.80 per pound to be mixed to get the final mixture for 2.10 per pound, hence:
2.4(35) + 1.8(x) = 2.1(x + 35)
x = 35 pounds

Answer:
2: x=6
3: x=5
Step-by-step explanation:
Question 1 is answered in the picture, but the answer is 6
<h2>Question 2:</h2>
x=14.3-(6.3+2)
x=14.3-8.3
x=6
<h2>Question 3:</h2>
x=20.6-(8.6+7)
x=20.6-15.6
x=5
2x-438 = -438+2x= 2(x-219)
