Solve for X<br><br> 2/3x+4=1/2x+5
mote1985 [20]

For this case we must find the value of the variable of the following equation:

\frac {2} {3} x + 4 = \frac {1} {2} x + 5

Subtracting \frac {1} {2} x from both sides:

\frac {2} {3} x- \frac {1} {2} x + 4 = 5\\\frac {4-3} {6} x + 4 = 5\\\frac {1} {6} x + 4 = 5

Subtracting 4 from both sides:

\frac {1} {6} {x} = 5-4\\\frac {1} {6} x = 1

Multiplying by 6 on both sides:

x = 6 * 1\\x = 6

Answer:

x = 6
