Question 1056452
If I am reading this right:
(1) {{{ 5p + 4a = 169 }}}
(2) {{{ 3p + 2a = 95 }}}
------------------------
Multiply both sides of (2) by {{{ 2}}}
and subtract (1) from (2)
(2) {{{ 6p + 4a = 190 }}}
(1) {{{ -5p - 4a = -169 }}}
-------------------------
{{{ p = 21 }}}
and
(2) {{{ 3*21 + 2a = 95 }}}
(2) {{{ 63 + 2a = 95 }}}
(2) {{{ 2a = 32 }}}
(2) {{{ a = 16 }}}
------------------------
21 pies and 16 batches of applesauce can be made
------------------------
check:
(1) {{{ 5p + 4a = 169 }}}
(1) {{{ 5*21 + 4*16 = 169 }}}
(1) {{{ 105 + 64 = 169 }}}
(1) {{{ 169 = 169 }}}
OK
