Question

08.03 MC)

Answer 1

Answer:

(5,38)

Step-by-step explanation:

The correct question is

A system of equations is shown below:

y = 8x − 2

y = 9x − 7

What is the solution to the system of equations?

(−5, 38)

(−5, −38)

(5, 38)

(5, −38)

we have

$y=8x-2$ ----> equation A

$y=9x-7$ ----> equation B

Solve the system by substitution

substitute equation B in equation A

$9x-7=8x-2$

solve for x

$9x-8x=7-2$

$x=5$

Find the value of y

Substitute the value of x in the equation A or in the equation B

$y=8(5)-2=38$

therefore

The solution is the point (5,38)
