Combine the variable (x) terms.

$x + 4 + 3 \times x = 72$ $x + 4 + 3 xx x = 72$

$4 \times x + 4 = 72$ $4 xx x + 4 = 72$ ; $4 \times x = 68$ $4 xx x = 68$ ; $x = 17$ $x = 17$

CHECK:
$x + 4 + 3 \times x = 72$ $x + 4 + 3 xx x = 72$ ; $17 + 4 + 3 \times 17 = 72$ $17 + 4 + 3 xx 17 = 72$

$21 + 51 = 72$ $21 + 51 = 72$ ; $72 = 72$ $72 = 72$ CORRECT!
