Mathematics

a = 18x

Step-by-step explanation:

Given

$\frac{1}{2}(a + d) = 10x$

$\frac{1}{2}(b + c) = 8x$

$\frac{1}{3}(b + c+d) = 6x$

Required

The value of (a)

We have:

$\frac{1}{2}(a + d) = 10x$ --- multiply by 2

$\frac{1}{2}(b + c) = 8x$ --- multiply by 2

$\frac{1}{3}(b + c+d) = 6x$ --- multiply by 3

So, we have:

$\frac{1}{2}(a + d) = 10x$

a + d = 20x

$\frac{1}{2}(b + c) = 8x$

b + c = 16x

$\frac{1}{3}(b + c+d) = 6x$

b + c + d= 18x

Substitute b + c = 16x in b + c + d= 18x

16x + d = 18x

Solve for d

d = 18x - 16x

d = 2x

Substitute d = 2x in a + d = 20x

a + 2x = 20x

Solve for (a)

a = 20x - 2x

a = 18x
