Tiana solved the equation -2(3x - 5) = 4(x + 3) + 8. When
she double checked her work
by substituting, it made the
equation untrue.

actually when I solved it ,the equation is true

Step-by-step explanation:

look

-2 (3x - 5) = 4(x + 3) + 8

-6x + 10 = 4x + 12 + 8

-6x + 10 = 4x + 20

-6x - 4x = 20- 10

-10x = 10

x = -1

and when I substitute, I get 16 on both sides so I don't know where the problem is

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

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.
