Pls help I’ll brainlest and add extra points ASAP solve it one step equation

1) a-2=10

add +2 to both sides to get a by itself

you get a = 12

2) 1/3n= 13

Make 1/3 into reciprocal 3/1

Multiply 3/1 to both sides

you get n= 39

3)  34= y/2

      Multiply 2 to both sides

      you get y= 68

4)  3/7n= 24

  Make  3/7 into reciprocal  7/3

    Multiply 7/3 to both sides

      you get 56

5)  x+2= 12

        -2   -2

x=  10

a-2=10

  +2  +2

a=12  

1/3n=13

•3     •3

n=39

34= y/2

•2   •2

68=y

3/7n=24

÷3      ÷3

1/7n=8

•7    •7

n=56  

w+2=12

   -2   -2

w=10

Step-by-step explanation:

easy math

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the answer is $42.96
