Answer:
x=4
Step-by-step explanation:
5(2x - 1) = 35
Should expand so....
10x - 5 = 35
10x = 40
x = 4
I will not give you the answer but I will show you how to solve this.
55*.6= A
65*.6=B
75*.6=C
85*.6 = D
Do you see the trend? Continue until ten equations are formed and add all of the totals. A+B+D+C...=Total
