Step-by-step explanation:
Answer:
1
Step-by-step explanation:
if there is just k, the number behind it is always 1
We are given with two equations X + y = k and <span>x - y = k. to find the solution of the </span>system<span> of linear equations, we can use elimination by adding the equations to eliminate y. hence the third equation is 2x= 2k ; x = k, hence y is equal to zero. Answer is C</span>
First, write an equation
x+7.9= 8.3
Now solve for x.
x=0.4
