Question

Make (a) the subject of the formula (a)
a/2c
+
b/4 = 2

Answer 1

To make (a) the subject of the formula (a), multiply both sides of the equation by 2c to eliminate the fraction, simplify the equation, and subtract (bc)/(2) from both sides to isolate a on one side.

Step-by-step explanation:

To make (a) the subject of the formula (a), we need to isolate a on one side of the equation.

Given the equation a/2c + b/4 = 2,

Multiply both sides of the equation by 2c to eliminate the fraction: 2c(a/2c) + 2c(b/4) = 2(2c)

Simplify the equation: a + (bc)/(2) = 4c

Subtract (bc)/(2) from both sides of the equation to move it to the other side: a = 4c - (bc)/(2)

Answer 2

a=8c-b/2

Step-by-step explanation:

a/2c+b/4=2

find the lcm

lcm=4c

multiply through by lcm 4c

4c×a/2c+4c ×b/4=4c×2

2×a+b×c=8c

2a+bc=8c

subtract bc from both sides

2a+bc-bc=8c-bc

2a=8c-b

To make 'a' subject of formula, divide 2 from both sides

2a/2=8c-b/2

a=8c-b/2
