Answer:
x=4, y=6, z=5
Step-by-step explanation:
x = 8/2 = 4
y = 12/2 =6
z = 10/2 = 5

For this case we convert the mixed numbers to improper fractions:
Now, we propose a rule of three:
pounds of blueberries ------------->
cups of muffin mix
7 pounds of blueberries -----------------------------> x
Where the variable "x" represents the number of cups of muffin mix that Honey should use.
So approximately Honey should use 
cups of muffin mix
Answer:
Approximately Honey should use cups of muffin mix
y = -2x + 9
y = 4x - 3
y is isolated in both equations, thus you may set the expressions (-2x + 9) and (4x - 3) equal to each other and solve for x.
-2x + 9 = 4x - 3
Subtract 9 from both sides.
-2x + 9 - 9 = 4x - 3 - 9
-2x = 4x - 12
Subtract 4x from both sides.
-2x - 4x = 4x - 12 - 4x
-6x = -12
Divide both sides by -6.
-6x/-6 = -12/-6
x = 2
Substitute 2 for x into one of the original equations to find y.
y = 4x - 3 (given)
y = 4(2) - 3 (substitute)
y = 8 - 3 (multiply)
y = 5 (subtract)
Plug x- and y-values into original equations to check work.
5 = -2(2) + 9
5 = - 4 + 9
5 = 5
5 = 4(2) - 3
5 = 8 - 3
5 = 5
Answer:
x = 2 and y = 5; (2, 5).
