Answer:

<h2>              y = 4</h2>

Step-by-step explanation:

x + 2y = 10    ⇒  2y - 10 = -x

-x + 4y = 14

2y - 10 + 4y = 14

6y = 24

 y = 4

Express x in terms of y! Find the value of x when y =5<br>2(x - 3)/y =5​
m_a_m_a [10]

Hey there!

2(x - 3) / y = 5

2(x - 3) / 5 = 5

2(x) + 2(-3) / 5 = 5

(2x - 6) 5 = 5

MULTPLY 5 to BOTH SIDES

(2x - 6)/5 * 5 = 5 * 5

SIMPLIFY IT!
2x - 6 = 5 * 5

2x - 6 = 25

ADD 6 to BOTH SIDES

2x - 6 + 6 = 25 + 6

SIMPLIFY IT!
2x = 25 + 6

2x = 31

DIVIDE 2 to BOTH SIDES

2x/2 = 31/2

SIMPLIFY IT!

x = 31/2

x = 15 1/2


Therefore, the answer should be:

x = 15 1/2


Good luck on your assignment & enjoy your day!
