What is the solution to the linear equation? d – 10 – 2d + 7 = 8 + d – 10 – 3d

d = 1 .

Step-by-step explanation:

Given : d – 10 – 2d + 7 = 8 + d – 10 – 3d.

To find : What is the solution to the linear equation.

Solution : We have given

d – 10 – 2d + 7 = 8 + d – 10 – 3d.

Combine like terms

d - 2d -10 + 7 = 8 -10 +d -3d .

-d - 3 = -2 -2d .

On adding both sides by 2d

-d + 2d -3 = -2 .

d - 3 = -2 .

On adding both sides by 3

d = -2 + 3.

d = 1 .

Therefore, d = 1 .

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
