3=5x-4+2x

help please :(

x=1

Step-by-step explanation:

3=5x-4+2x

collect the like terms

3=7x-4

Move terms

-7x=-4-3

Calculate

-7x=-7

Divide both sides by -7

x=1

X=1

Step-by-step explanation:

First lets combine like terms.

3=7x-4 (2x and 5x can be combined.)

Next, isolate your X variable.

7=7x (when you move a variable to the other side of the equation it gains the opposite sign Ex:-4 would become 4 and 4 would become -4)

Finally, find out what you need to multiply with x to get 7.

You need to multiply 1 with 7 to get 7.

The answer is x=1

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
