Answer:
10
Step-by-step explanation:
2(4y-5)= 70
4y-5= 70/2
4y-5= 35
4y = 35 +5
4y = 40
y= 40/4
y= 10
First you distribute so two times 4Y is 6Y then you multiply the two in the five which gives you 2Y -5 equals 70
6
divide into
keep change flip
and we get 9/2 * 4/3 which gives us 3*2 = 6
1/2(12w+8) -1/5(10w-5) = 4w + 3 or 4w + 5
( im kinda confused on this myself)
