Question

Solve ax+by = a+b & x + y = 2

Answer 1

Answer:

x=1,y=1

Step-by-step explanation:

x+y=2. x=2-y. a(x)+by=a+b. a(2-y)+by=a+b. 2a-ay+by=a+b. y(-a+b)=a+b-2a. y=(-a+b)/(-a+b). y=1. x+1(y)=2. x=2-1×1. x=2-1. x=1

Answer 2

Answer:

1

Step-by-step explanation:

ax + by = a + b --------------(1)

we have,

x + y = 2

bx + by = 2b ----( multiplying by b) ----(2)

we solve equation (1) and (2) --

we get x = 1 and y = 1
