What is (4x+-7) (2x+-9)

Answer:x=1

Step-by-step explanation: (4x+-7) = (2x+-9)

We move all terms to the left:

(4x+-7) - ((2x+-9)) = 0

We add all the numbers together, and all the variables

(4x-7) - ((2x-9)) = 0

We get rid of parentheses

4x - ((2x-9)) - 7=0

We calculate terms in parentheses: - ((2x-9)), so:

(2x-9)

We get rid of parentheses

2x-9

Back to the equation:

- (2x-9)

We get rid of parentheses

4x-2x+9-7=0

We add all the numbers together, and all the variables

2x+2=0

We move all terms containing x to the left, all other terms to the right

2x=-2

x=-2/2

x=-1

(4x+-7) = (2x+-9)

We move all terms to the left:

(4x+-7) - ((2x+-9)) = 0

We add all the numbers together, and all the variables

(4x-7) - ((2x-9)) = 0

We get rid of parentheses

4x - ((2x-9)) - 7=0

We calculate terms in parentheses: - ((2x-9)), so:

(2x-9)

We get rid of parentheses

2x-9
