Question

Solve the simultaneous equations

x+5y=16
x+3y=10

Answer 1

Answer:

x=1, y=3

Step-by-step explanation:

x+5y=16....(1)

x+3y=10....(2)

Subtracting equation 2 from equation 1 we have,

   (x+5y)-(x+3y) = 16-10

=>(x - x) + (5y - 3y) = 6

=>2y = 6

=> y = 3

Replacing value of y in equation 2 we have,

x+3(3) = 10

=> x+9 = 10

=> x=1

Therefore, value of x is 1 and y is 3.

Answer 2

Answer: y= 3

Step-by-step explanation:

X+5y=16

X+3y=10

Solution

Step 1. X+5y=16

X+3y=10

Step 2. X+5y=16

-x-3y= - 10

Step 3. 2y= 6 then divide 2 by both sids

The result will be y= 3 only.
