Answer:
Step-by-step explanation:
Let:
We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 4 and (2) by 3:
Now subtract 3*(2) from 4*(1) in order to eliminate x:
Solving for y:
Multiplying both sides by -1/13
Finally, replacing the value of y in (1)
Solving for x:
add 2 to both sides:
Multiply both sides by 1/3:
A
i solved it
240
! means factorial or to multiply by the previous number down to one so 5!=5*4*3*2*1=120 120*2=240.
