270 divide by 200 = 1.35
1 euro = 1.35 dollars
1.35 x 300 = 405 dollars

Answer: x = 2
Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.
So we have 4(x) which is 4x and 4(6) which is 24.
So our equation now reads 4x + 24 = 32.
Solving from here, we subtract 24 from both sides to get 4x = 8.
Then divide both sides by 4 to get <em>x = 2</em>.
Let
x = loaves of bread
y = batches of muffins
You must make a system of two equations with two unknowns that describe the problem
3.5x + 2.5y = 17 --- (1)
0.75x + 0.75y = 4.5 --- (2)
Resolving we have
x = 6-y (from (2))
replacing in (1)
3.5 (6-y) + 2.5y = 17
21 - 3.5y + 2.5y = 17
y = 21-17 = 4
Then substituting in (2)
x = 6-y = 6-4 = 2
