Answer: x = 11
Step-by-step explanation:
<em>first, i did simple calculations.</em>
4x(2) = 88
<em>that calculates out to: </em>
8x = 88
<em>then, i divided both sides by 8, in order to get x by itself.</em>
8x/8 = 88/8
x = 11
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
