Why are there different time lines

Let's solve your equation step-by-step.

7−3x=x−4(2+x)

Step 1: Simplify both sides of the equation.

7−3x=x−4(2+x)

7+−3x=x+(−4)(2)+(−4)(x)(Distribute)

7+−3x=x+−8+−4x

−3x+7=(x+−4x)+(−8)(Combine Like Terms)

−3x+7=−3x+−8

−3x+7=−3x−8

Step 2: Add 3x to both sides.

−3x+7+3x=−3x−8+3x

7=−8

Step 3: Subtract 7 from both sides.

7−7=−8−7

0=−15

There are no solutions.

Let's solve your equation step-by-step.

5(3x+5)=3(5x+1)

Step 1: Simplify both sides of the equation.

5(3x+5)=3(5x+1)

(5)(3x)+(5)(5)=(3)(5x)+(3)(1)(Distribute)

15x+25=15x+3

Step 2: Subtract 15x from both sides.

15x+25−15x=15x+3−15x

25=3

Step 3: Subtract 25 from both sides.

25−25=3−25

0=−22

There are no solutions.
