Answer:
x = 11/2
Step-by-step explanation:
solve : 2x-6 = 5
2x-6+6= 5+6 add 6
2x = 11 divid by 11
x = 11/2
Answer:
8.5
Step-by-step explanation:
Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:
2(x-6)=5
(x-6)=5/2
x=6+5/2
x=17/2
So the number is 17/2, or, expressed as a decimal number, 8.5
