Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.
To write the coefficients of the 8 terms, either start with a combination of 7 things taken 0 at a time and continue to 7 things taken 7 at a time or use the 7th row of Pascal’s triangle.
For the first term, write x to the 7th power and 3 to the 0 power. Then decrease the power on x and increase the power on y until you reach x to the 0 and y to the 7.
Simplify by evaluating the coefficients and powers 3

Answer:
You take 13x25x11 or as i like to do it take the lowest numbers and multiply them first like this so take 13x11=143 then times that by 25! 143x25=3575!
Step-by-step explanation:
You take all the numbers and multiply them like said in the answer!
Hope This Helped!
