Question 1107853
ax - 5b = 3x + 2
ax - 3x = 5b + 2   (added 5b to both sides, subtracted 3x from both sides)
x(a - 3) = 5b + 2   (factored the common x from left hand side)
x = (5b + 2)/(a - 3)    (divided both sides by a - 3)

Solution:   {{{ highlight(matrix(1,3, "x", " = ", (5b + 2) / (a-3)) ) }}} ,   with the restriction {{{ a-3 <> 0 }}}
