Solve the system of equations by substitution, y = 2x - 4
y = x + 1

a.(2,3)
b.(5,6)
c.(4,8)
d.(3,1)

The solution to the system of equations is:

(x, y) = (5, 6)

Hence, option B is correct.

Step-by-step explanation:

Given the system of equations

y = 2x - 4

y = x + 1

Solving the system of equations by substitution method.

Substitute y = x+1 in y = 2x - 4

Subtract 1 from both sides

Simplify

Subtract 2x from both sides

Simplify

Divide both sides by -1

Simplify

For y = x+1

substitute x = 5

Simplify

Therefore, the solution to the system of equations is:

(x, y) = (5, 6)

Hence, option B is correct.

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
