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
Answer:
The value of x is 4
Step-by-step explanation:
y = 2.5x + 65; y = 75
Now, Substitute
y = 2.5x + 65
75 = 2.5x + 65
75 – 65= 2.5x + 65 – 65
10 = 2.5x
2.5x = 10
2.5x/2.5 = 10/2.5
x = 4
Thus, The value of x is 4
