Question

An equation is shown. 3x + 4/5 = 7 – 2x What is the solution to the equation? x=

Answer 1

Answer:

x= 1.24

Step-by-step explanation:

First step is to move the variable to one side. To do that, the smallest variable needs to be subtracted or added.

3x+4/5= 7-2x

+2x           +2x

Now that it has been moved to one side, isolate the variable. Subtract 4/5 to both sides.

5x+4/5= 7

    -4/5 -4/5

(4/5 is 0.80, so subtract 0.80 from 7)

5x= 6.2

Now divide 5 to both sides.

5x=6.2

5     5

x= 1.24

Answer 2

Answer:

Step-by-step explanation:

3x + 4/5 = 7 – 2x

Multiply each term by 5

15x + 4 = 35 -10x

15x + 10x = 35 - 4

25x = 31

x = 31/25

x = 1 6/25
