Answer :
Answer:
(a)
Step-by-step explanation:
given the equation
[tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{4}[/tex] y = z + 3
multiply through by 4 ( the LCM of 2 and 4 ) to clear the fractions
2x + y = 4z + 12 ( subtract 2x from both sides )
y = 4z - 2x + 12
a. y = 4z - 2x + 12
Given the equation:
1/2x + 1/4y = z + 3
Solve for y.
1/2x + 1/4y = z + 3
Subtract 1/2x from both sides.
1/4y = z + 3 - 1/2x
Multiply both sides by 4 to get y.
y = 4(z + 3 - 1/2x)
y = 4z + 12 - 2x
