Question

if x = 10 and x +2y = 200.find x if 2y - 50 = x​

Answer 1

Answer:

y = 30

Step-by-step explanation:

2y - 50 = 10

Move all terms not containing y to the right side of the equation.

Add 50 to both sides.

2y = 10 + 50

Add 10 and 60

2y = 60

Divide each term by 2 and simplify.

Divide each term in 2y = 60 by 2.

$\frac{2y}{2} =\frac{60}{2}$

Cancel the common factor.

$y=\frac{60}{2}$

Divide 60 by 2.

y = 30
