Which statements are true the order pair (1,2) and the system of equations?
y=2x+4
7x-2y=3

The Correct Answers are

When (1 ,2) is substituted into the first equation, the equation is true.

When (1 ,2) is substituted into the second equation, the equation is true.

When (1 ,2) is substituted into the second equation, the equation is true.

Step-by-step explanation:

Given:

..............Equation ( 1 )

.............Equation ( 2 )

To Show:

order pair ( 1, 2) True for Which Equation

Solution:

The Correct Statements are

When (1 ,2) is substituted into the first equation, the equation is true.

For Equation ( 1 )

Put x = 1 and y =2 in equation 1 we get

∴ Left hand side = Right hand side

Hence True

When (1 ,2) is substituted into the second equation, the equation is true.

For Equation ( 2 )

Put x = 1 and y = 2 in equation 2 we get

∴ Left hand side = Right hand side

Hence True

The ordered pair (1 , 2) is a solution to the system of linear equations.

∴ From above Both are True,

Hence True

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

pretty sure 750 each month!
