Question 988937
(1) {{{ 5x - 3y =1 }}}
(2) {{{ 2x + y = 8 }}}
-------------------
Multiply both sides of (2) by {{{ 3 }}}
and add the equations
----------------------
(1) {{{ 5x - 3y =1 }}}
(2) {{{ 6x + 3y = 24 }}}
----------------------
{{{ 11x = 25 }}}
{{{ x = 25/11 }}}
-----------------
plug this result into (1)
(1) {{{ 5*(25/11) - 3y =1 }}}
(1) {{{ 125 - 33y = 11 }}}
(1) {{{ 33y = 114 }}}
(1) {{{ y = 38/11 }}}
---------------------
check:
(2) {{{ 6*(25/11) + 3*(38/11) = 24 }}}
(2) {{{ 150 + 114 = 264 }}}
(2) {{{ 264 = 264 }}}
