if 10+5y=77 then what is y?
10+5y=77
5y = 77 - 10
5y = 67
y = 67/5
y = ?
10+5y=77
Subtract 10 from both sides.
5y=67
Divide both sides by 5.
y=67/5
what??? i don't get it:(
What part of either Jen's or my explanation don't you get?
isnt it 13.4?? cause if you do 67/5 you get 13.4
You're right.
67/5 = 13.4
y = 13.4
To prove it, substitute 13.4 for y in the original equation.
ok thank you
You're welcome.
To find the value of y in the equation 10 + 5y = 77, we can solve it algebraically using the following steps:
Step 1: Start with the equation: 10 + 5y = 77.
Step 2: Subtract 10 from both sides of the equation to isolate the term with y:
10 + 5y - 10 = 77 - 10
5y = 67
Step 3: Divide both sides of the equation by 5 to solve for y and get it alone:
5y/5 = 67/5
y = 67/5
Therefore, the value of y is 67/5, which is equivalent to 13.4 or can be written as a mixed number, 13 2/5.
