Question

Be sure to distribute and collect like terms before you solve.
2(4x + 3) - 9 = 45

Answer 1

x=6

Answer 2

@DUDE..LOOK..ITS..SGTC
What use is giving "6" as an abswer

OP will just have to ask for the NEXT answer and has learned nothing

Answer 3

sorry, hold on

Answer 4

@ThebigbossAsb20 the question gives you hints:

"distribute" means expand the bracket - multiply the 2 by the elements inside:

2(4x+3) = 2*4x +2*3

write the original equation having expanded as I showed above ...

Answer 5

First, let's work on the left hand side of your equation, the 2(4x+3)-9
This means, for instance, to see if it can be simplified at all.
Multiply x and 4
Multiply x and 1
The x just gets copied along.
The answer is x
x
4*x evaluates to 4x
4*x+3 evaluates to 4x+3
Multiply 2 by 4x+3
we multiply 2 by each term in 4x+3 term by term.
This is the distributive property of multiplication.
Multiply 2 and 4x
Multiply 1 and x
The x just gets copied along.
x
2 × 4x = 8x
Multiply 2 and 3
1
2 × 3 = 6
2*(4*x+3) evaluates to 8x+6
6 - 9 = -3
The answer is -3+8x
2*(4*x+3)-9 evaluates to -3+8x
So, all-in-all, the left hand side of your equation can be written as: -3+8x
________________________________________
Now, let's work on the right hand side of your equation, the 45
The right hand side of your equation can be written as: 45
________________________________________
So with these (any) simplifications, the equation we'll set out to solve is:
-3+8x = 45

Move the -3 to the right hand side by adding 3 to both sides, like this:
To the left hand side:
-3 + 3 = 0
The answer is 8x
To the right hand side:
45 + 3 = 48
The answer is 48

Now, the equation reads:
8x = 48
To isolate the x, we have to divide both sides of the equation by the other variables
around the x on the left side of the equation.
________________________________________
The last step is to divide both sides of the equation by 8 like this:
To divide x by 1
The x just gets copied along in the numerator.
The answer is x
8x ÷ 8 = x
48 ÷ 8 = 6
The solution to your equation is:
x = 6
