how do you do these algebra 1 questions?

sharoz s here it is

1.) 11=m+1

this is finding the value of m

so removed + 1 beside m by adding -1 to the left of the equal sign and the right

-1 + 11 = m + 1 - 1

10 = m + 0

so → m = 10

2.)m/4 =6

here remove the /4 under m by making it 1(one)

how: → multiply 4 to the left side of equal sign and to the right side too

4 x m/4 = 6 x 4

4 cancel out making it 1(one) . one time m = m

so → m = 24

3.) 21=7y

here remove the 7 beside the y by making it 1(one)

how: → divide by 7 to the left side of the equal sign and to the right too.

12/7 = 7/7(y)

12/7 = 1(y)

y = 12/7

hope this helps

1) 11=m+1

-1 -1 (Addition Property of Equality)

10=m

2) m/4=6

*4 *4 (Division Property of Equality)

m=24

3) 21=7y

/7 /7 (Divided by 7) (MultiplicationProperty of Equality)

3=y

I'm in pre algebra..

1) 11=m+1

11-1=10 sooo m=10

2)m/4=6

4*6=24

24/4=6 sooo m=24

21=7y

21/7=3

check it....7(3)=21

sooo y=3

hoped i helped!!!!

1. 11=10+1

3. y =3

dont know 2 im only in grade 6

how to answer number one:

11=m+1

first you transpose the +1 to the other side by making the equation to

11-1=m+1-1

therefore making the equation: 10=m, or m=10

how to answer number two:

m/4=6

you multiply both sides of the equation by 4 to get: m= 24

how to answer number three:

21=7y

you divide both sides of the eqation by 7 to get:

y=3

You have to isolate the variable. So for the first one you must isolate m to do this you subtract 1from both sides to get m=10. For the second one you multiply 4 form both sides to get m=24. For the last one you must isolate Y by dividing both side by 7 to get y=3
