Simplify the expression below: 3(2x - 5) - (4x + 1) +2(6 – 5x + 2x)
into the form AX + B
1. What is the value of A?
Do not include spaces, units, or commas in your response.
2. What is the value of B
Do not include spaces units, or commas in your response.

The value of A is -4, and that of B is -10

Step-by-step explanation:

We must carry out the indicated multiplication (and removal of parentheses) according to Order of Operations rules:

6x - 15 - 4x - 1 + 6 - 10x + 4x

Grouping like terms together, we get:

6x - 4x - 10 x + 4x  -  15  -1 +    6

this, in turn, simplifies to:

-4x-10

The value of A is -4, and that of B is -10

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
