1- rearrange terms
29+5x=4
5x+29=4
Subtract 29 from both sides since it don’t have the variable
5x=-25
Divide by 5 to get individual X.
X= -5

2- rearrange terms
3x+21=51
Subtract 21 from both sides.
3X=30
Divide by 3.
X= 10

3) rearrange terms.
5x+13=33
Subtract 13.
5x=20
Divide by 5.
X=4

4) -3X+47=32
Subtract 47 from both sides.
-3x=-15
x=5

5) -11x+157=69
Subtract 157
-11x=-88
Divide by 11.
x= 8

6-
1x+72=82
subtract 72.
1x=10
Divide by 10.
X=10

Explanation:

sum -- the result of addition: 5x+1

term -- a constant, variable, or product of a constant and one or more variables. In the more general sense, a term is any part of the expression that can be considered by itself. An example is 5x

product -- the result of multiplication: 9(5x+1), where 9 is multiplied by the sum (5x+1)

factor -- part of a product: x

quotient -- the result of division: 9(5x+1)÷3

coefficient -- a constant, or the constant that multiplies the variables in a term: 5

_____

<em>Additional comment</em>

The way this is written, there will be the tendency to think of 3y as a term in the same sense that 5x is a term. That would be incorrect. The Order of Operations has you interpret this expression as ...

  \dfrac{9(5x+1)}{3}\cdot y

Substitute x = (- 1 + 2√2)/4 in the equation (4x + 1)² - 8 = 0 and check whether the value satisfies the given equation.
kow [346]

The value of  x = (- 1 + 2√2)/4 satisfies the given equation.

<h3>What is an Equation ?</h3>

An equation is a mathematical statement formed when two algebraic expressions are equated by an equal sign.

The equation given is

(4x + 1)² - 8 = 0

x =  (- 1 + 2√2)/4

To check whether it satisfies the equation

( 4 * ( (- 1 + 2√2)/4) +1)² -8 = 0

(-1 + 2√2  +1)² - 8 = 0

(2√2)² -8 = 0

8-8 = 0

As LHS = RHS ,

hence the value of  x = (- 1 + 2√2)/4 satisfies the given equation.
