Question

Find x:
x + x + 375 = 450
Find y:
2y + 700 = 4y + 105

Answer 1

Answer:

the value of x is 37.5 and the value of y is 297.5.

Answer 2

x solution:

$x + x + 375 = 450 \\ 2x =450 - 375 \\ 2x = 75 \\ x = \frac{75}{2} \\ x = 37.5$

y solution:

$2y + 700 = 4y + 105 \\ 700 - 105 = 4y - 2y \\ 595 = 2y \\ y = \frac{595}{2} \\ y = 297.5$

Hope it helps
