Question

Find the value of x and y.If the eqns. are x+14=4 and y+x=15

Answer 1

equation 1
x + 14 = 4
x = 4-14 = -10
x = -10
equation 2
x+y = 15
put the value of x = -10
-10 + y = 15
y = 15+10
y = 25
so x = -10 , y = 25

Answer 2

x plus14=4-------1

y+x=15-------------2

subtract

x+y=4

x+y=15

- - -

----------

0 +y=-11

--------------

-y=-11-14

y=25

put in 2

25+x=15

x=15-25

x=-10
