Answer

Problem

Solve the equation:
\$ 25/3(x+1) = 2/3(x-3) \$

Step

Cancelling denominator values on both sides

\$ 25/\cancel(3)^1(x+1) = 2/\cancel(3)^1(x-3) \$

Step

After Cancellation

25 (x+1) = 2 (x-3)

Step

After Multiplication

25 x + 25 = 2 x - 6

Step

Move Constant terms to right side
Variable terms to left side

25 x - 2 x = -6 - 25

Step

Taking common term: x

(25 - 2) x = -6 - 25

Step

After subtraction

23 x = -31

Step

Dividing with 23 on both sides

\$ (\cancel(23)x)/\cancel(23) = -31/23 \$

Step

After Cancellation

\$ x = -31/23 \$
