Answer 1

Answer:

2(x-4)+3(x+9)=-1

Multiply them : 2x - 8 + 3x + 27 = -1

Now Solve :

5x + 19 = -1

Answer 2

Given:

2(x - 4) + 3(x + 9) = -1

What To Do:

We have to solve the equation and find the value of x.

Solution:

2(x - 4) + 3(x + 9) = -1

Remove the brackets and solve,

⇒ 2x - 8 + 3x + 27 = -1

Rearrange the like terms,

⇒ 2x + 3x - 8 + 27 = -1

Solve those rearrange terms,

⇒ 5x + 19 = -1

Take 19 to RHS,

⇒ 5x = -1 - 19

Subtract 19 from -1,

⇒ 5x = -20

Take 5 to RHS,

⇒ x = $\dfrac{-20}{5}$

Divide -20 by 5,

⇒ x = -4

∴ So, the value of x is -4.

To verify:

2(x - 4) + 3(x + 9) = -1

Substitute the value,

⇒ 2((-4) - 4) + 3((-4) + 9) = -1

Solve the brackets,

⇒ 2(-8) + 3(5) = -1

Remove the brackets,

⇒ -16 + 15 = -1

Add the number in LHS,

⇒ -1 = -1

∴ LHS = RHS

∴ Hence, verified.
