Question

a) 1.100 b) 1: iii) If 3x + 5y = 9 and 5x + 3y = 7 then What is the value of x +y? + iv) If m + 3 = 5 then m =​

Answer 1

Answer: According to the question : x+y=2 and value of m is 2.

Step-by-step explanation: we are given two equations i.e., 3x+5y=9 and 5x+3y=7

On adding these two equations. We get,

8x+8y=16

Taking 8 common from RHS

8(x+y)=16

8 will be divided by 16.

x+y=2

Hence, the value of x+y is 2.

In second part of the question, we are given m+3=5

To find the value of m,

m=5-3

m=2

Hence, the value of m is 2.
