Question : 8 ( x + 2) - 4x + 7
Solve:
To simplify this equation, the first thing u need to do is multiply 8 into ( x + 2) which will show like this : 8x +16 - 4x + 7
and now we'll simplify it by adding and subtracting the numbers go with x and the ones without x : 8x - 4x +16 + 7 (This's the same one to the above one, i just move the number around so you could see which numbers go with x and which do not)
Then we'll solve it: (8x - 4x) + (16 + 7)
= 4x + 23
The answer is 4x + 23

Okay, so first you need to simplify the equation....I think you'd use the distributive property and the equation would become. 8x+16-4x+7. You would then (I think) use the commutative property and switch the numbers around to 8x-4x+16+7. Now you can solve 8x-4x by saying it is 4x (8-4=4), and you would add 16 to 7 to equal 23. Your answer would be 4x+23. You cannot simplify it anymore. Hope you get it right!

8(x+2)-4x+7 ----you need to do the brackets followed by the multiply, so:
8x + 16 - 4x +7 = 4x +23

step 1: multiply the 8 by everything in parentheses.
You get: 8x + 16 -4x +7
step 2: combine like terms. Combine your variables together, and
then your numbers.
You get: (8x -4x) = 4x and then (16 + 7) = (+) 23
step 3: place variables at beginning of solution and numerals at
the end.
You get: 4x + 23
And that is your answer: 4x + 23
Hope I helped. Have a nice day :)

8(x+2)-4x+7
8 times x and 2
8x+16-4x+7
now combine like terms
8x-4x=4x
16+7=23
which is 4x+23

8x + 16 - 4x +7
8x-4x=4x
4x+16+7
16+7=23
4x+23= final answer
4x+23
