Answer:
i dont know sorry
Step-by-step explanation:
Solve by the elimination method
x/5 + y = 6/5
x/10 + y/3 = 7/10
x + 5y = 6 |×2| 2x + 10y = 12
3x + 10y = 21 |×1| 3x + 10y = 22
__________ -
-x = -10
x = 10
x + 5y = 6
10 + 5y = 6
5y = 6 - 10
5y = -4
y = -4/5
Solution → (x,y) = (10 , -4/5)
Method 1:
First do the operation inside parenthesis
2*(4-3) = 2*1 = 2
Method 2:
Use distributive property: a*(b +c) = a*b + a*c
2*(4-3) = 2*4 - 2*3
= 8 - 6
= 2
