answer:
A is your answer...
explanation:
I just divided each number by 4 to get the results..
hope it helps and plz mark brainliest
The answer is 23 because they have to add up to 90 :) - beanz
2x + 4(x - 1) = 2 + 4x
2x + 4x - 4 = 2 + 4x
6x - 4 = 2 + 4x
6x - 4x = 2 + 4
2x = 6
x = 3........there is 1 solution
25 - x = 15 - (3x + 10)
25 - x = 15 - 3x - 10
25 - x = -3x + 5
3x - x = 5 - 25
2x = - 20
x = -20/2
x = -10.....there is 1 solution
4x = 2x + 2x + 5(x - x)
4x = 4x + 5x - 5x
4x = 4x......this has infinite solutions
learn this...
if ur equation ends in a variable equaling a number, then there is one solution.
if ur equation ends in something not equal, like 2 = 4, or 4 = 6, then there is 0 solutions.
if ur equation ends in something equal to something,(the same) like 2 = 2, or 4x = 4x, then there is infinite solutions
- 15
- about 94.25
- about 706.86
Lmk if you want to know how I got the answers
Answer: you just flip it. It would be the opposite.
Step-by-step explanation:
When you flip it, what’s the difference? It’s still the same.
