Step-by-step explanation:
We are going to do a replacement of x for a second equation
So instead
in the place of x we are putting 12-y from the first equation, so
To leave the brackets we need to do multiplication
Which is
How to determine x? From the first equation:
If the x +y = 12 then the x = 12-y so x = 12-7 = 5
We should write solution as a pair:
Answer:
I believe it's the second one
Step-by-step explanation:
The greatest common factor of 44 and 40 is four, so 4 times 11 is 44 and 4 times 10 is 40. that gives you 44 + 40
Answer:
Step-by-step explanation:
- 20 - 15(2²· 5/4) = Exponent
- 20 - 15(4 · 5/4) = Parenthesis
- 20 - 15(5) = Multiplication
- 20 - 75 = Subtraction
- - 55
Answer:
