Question 1098769
Let {{{ a }}} = cost of 1 pound of peanuts in dollars
Let {{{ b }}} = cost of 1 pound of cashews in dollars
----------------------------------------
(1) {{{ 5a + 6b = 11.2 }}}
(2) {{{ 3a + 7b = 10.8 }}}
--------------------------
(1) {{{ 50a + 60b = 112 }}}
(2) {{{ 30a + 70b = 108 }}}
--------------------------
(1) {{{ 25a + 30b = 56 }}}
(2) {{{ 15a + 35b = 54 }}}
--------------------------
Multiply both sides of (1) by {{{ 15 }}}
Multiply both sides of (2) by {{{ 25 }}}
Subtract (1) from (2)
