What is the solution for x in the equation? -x + 3/7 = 2x - 25/7

x= 3/4 or 0.75

Step-by-step explanation:

multiply by 7

-7x+3= 14x-25

3=21x-25

28=21x

x=3/4

x=4/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−x+3/7=2x+−25/7

Step 2: Subtract 2x from both sides.

−x+3/7−2x=2x+−25/7−2x

−3x+3/7=−25/7

Step 3: Subtract 3/7 from both sides.

−3x+3/7−3/7=−25/7−3/7

−3x=−4

Step 4: Divide both sides by -3.

−3x/−3=−4/−3

x=4/3

0.02
