Question 511509
Call the mystery number {{{x}}}
given:
Sarah's beads:
{{{ 4x + 3 }}}
Jasmine's beads:
{{{ 5x - 9 }}}
(a)
They had the same number of beads, so
{{{ 4x + 3 = 5x - 9 }}}
(b)
Subtract {{{ 4x }}} from both sides
{{{ 3 = x - 9 }}}
Add {{{ 9 }}} to both sides
{{{ 12 = x }}}
or,
{{{ x = 12 }}}
