Question

Solve for x and y:x/10+y/5=14 and X/8+y/6=15

Answer 1

Step-by-step explanation:

Given equations:

x/10+y/5=14......eqn (1)

x/8+y/6=15 ....... eqn (2)

eqn (1)×5 - eqn (2)×6; we get,

(x/2)+ y- (3x/4)- y= 70- 90

=> -x/4= -20

=> x= 80

put the value of x in eqn (1); we have:

(80/10)+ y/5= 14

=> y/5= 6

=> y = 30

Therefore, the value of x is 80 and the value of y is 30.

Hope, it helps!
