Answer:

<h2>( 5, 0 ) </h2>

Step-by-step explanation:

x - 3y = 5

2x + y = 10 multiply by 3 to eliminate y and solve for x

x - 3y = 5

<u>6x + 3y = 30</u> then add

7x = 35

simplify:

x = 35 / 7

x = 5

substitute x = 5 back into the eq.2

2x + y = 10

2(5) + y = 10

y = 10 - 10

y = 0

therefore the answer is ( 5, 0 )

3(x + 1) = 5(x - 2) + 7

Distribute 3 and 5 inside their respective parentheses.

3x + 3 = 5x - 10 + 7

Combine like terms.

3x + 3 = 5x - 3

Add 3 to both sides.

3x + 6 = 5x

Subtract 3x from both sides.

6 = 2x

Divide both sides by 2.

<h3>x = 3</h3>
