what do brackets mean in algebra? ie, [6 (4x-7) + 3 (12x + 8) ]?

Answer 1

Brackets as parentheses are a way of grouping terms, that's all.
.

Answer 2

As I Understoot from the question that's going to likely be 6-3( 4x-5)=7 as a result it is going to be multiply the numbers out element the bracket with the numbers in element the bracket, then upload like term and shop the huge sort 7 in that's beginning place place and circulate the huge sort 15 to the main stunning fringe of the equation , then the version of 15 and seven devide with the aid of the huge sort that's elevated with the aid of x. like. 6-3(4x-5)=7 24x-12x-30+15 = 7 then, 12x - 15 = 7 then circulate 15 to the main stunning 12x= 7+15 then x= 22/12 then x= 11/6 or a million.80 3

Answer 3

You do that computation first. In math, you don't work left to right but you do multiplication and division and then addition and subtraction. So 6 (4X-7), if x was 2, would be 6, {6*the problem in the brackets, 8-7, leaving 6*1} but without the brackets, it would be 41. {6*4x or 6*8 = 48 then subtract 7 leaving 41}

Answer 4

6 multiplies 4x - 7 and 3 multiplies 12x + 8
= (24x - 42) + (36x + 24)
= 60x - 18
= 6.(10x - 3) if desired in this form.

Answer 5

Please excuse my dear aunt Sally

I used to say this to remember the order of operations!

Paranthesis
Exponets
Multiplication
Division
Addition
Subtraction

So, if you have brackets, do the operations in that order in the brackets to come up with the final number that the bracket equals!!

Hope this helps!

Answer 6

Brackets are the same as parenthesis. In your example, the brackets have no meaning at all and are unneccessary.

Answer 7

Group.

Answer 8

brackets are a way of grouping equations, but also tell you to do those parts of the equation first.

Answer 9

the brackets tell you what to do after you do the work in the parentheses
