The xxx symbolic xxxxxxxxxx xxx xxxxxxxxxxx and Substitution xxxxxxx xxxx to solve xxxxxx xxxxxxxxxx

Both xxx better xx xxxxxxx xxxxxxxxxx xxx example, xx it is xxxx xx xxx up an equation for xxxxxxxxxxxx where 1 variable is on x xxxxxxxxx use xxxxx For xxxxxxxx xx you xxxx x = y + x and

xx x x x xx xxxx xx xxx xx easier for you to xxxx plug the value

of x xxxx the xxxxxxxx and xxxxxx

xx other xxxxx xxxxx it may not be xx xxxx (Fractions/decimals, etc.), xxxx we would probably rather use elimination method

xxx xxxxxxxxxx xx have xxxxxx xxxxxxxxxxxxx xxx xxxxxx =67 xxxxxxxxx ,then

Substracting (2) xxxx xxx xx get xx

xxxxxxxxxxxxx = 79-67

xxx 12

xxx xxx xx 5 {by xxxxxxxxxxxx xxx xxxxx xx y xx eq(1)}

So,both are required xxxxxxxxx xxx the single xxxxxxxx xx xxxxxxx xx xxx xxxxxxxx xxx xxx xxx we would like xx solve xxxx

xx
