PLS HELP! GIVING BRAINLIST! y = x - 2

y = 3x + 4

Is (4,2) a solution of the system?

We conclude that (4, 2) is NOT a solution to the system of equations.

Step-by-step explanation:

Given the system of equations

Important Tip:

Let us solve the system of equations using the elimination method.

Arrange equation variables for elimination

Subtract the equations

Now, solve -2x = 6 for x

Divide both sides by -2

Simplify

For y - x = -2 plug in x = -3

Subtract 3 from both sides

Simplify

The solution to the system of equations is:

(x, y) = (-3, -5)

Checking the graph

From the graph, it is also clear that (4, 2) is NOT a solution to the system of equations because (-3, -5) is the only solution as we have found earlier.

Therefore, we conclude that (4, 2) is NOT a solution to the system of equations.

the answer would be 0.54

60: 45 =12: 9 =4: 3 so the answer is 4: 3
