Answer:
85/7
Step-by-step explanation:
log2 + log7(x-5) = 2
log(14(x-5)) = 2
14x - 70 = 10²
14x = 170
x = 170/14
x = 85/7 or 12 1/7
Answer:
x=6
Step-by-step explanation:
7+5 (x-3)=22
Subtract 7 from each side
7-7+5 (x-3)=22-7
5(x-3) = 15
Divide each side by 5
5(x-3)/5 = 15/5
x-3 = 3
Add 3 to each side
x-3+3=3+3
x=6
