Answer:
Step-by-step explanation:
7y+5+3y+5=70
10y+10=70
10y=60
y=6
7(6)+5= 42+5= 47
3(6)+5= 18 + 5 =23
47+23= 70
Y + 0.4 = 2 .....subtract 0.4 from both sides
y = 2 - 0.4
y = 1.6 <==
Answer:
y=5x-10
Step-by-step explanation:
5x - y = 10
-y = -5x + 10
y = 5x -10
-9 because 2+7=9 so the negative part oh then must be -9
