solve the simultaneous equations of x+y =8 and x-y=2​

Sagot :

Answer:

(5, 3 )

Step-by-step explanation:

Given the 2 equations

x + y = 8 → (1)

x - y = 2 → (2)

Adding the 2 equations term by term will eliminate the y- term

2x + 0 = 10

2x = 10 ( divide both sides by 2 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (1)

5 + y = 8 ( subtract 5 from both sides )

y = 3

solution is (5, 3 )
