---   ---

2      2

x = 7

Hey!

------------------------------------------------

Steps To Solve:

2x - 4 = 10

~Add 4 to both sides

2x - 4 + 4 = 10 + 4

~Simplify

2x = 14

~Divide 2 to both sides

2x/2 = 14/2

~Simplify

x = 7

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.
