Question

x/2-10 +x-15+3x/2 -15=180 find the value of x​

Answer 1

Answer:

$220 \div (2 \sqrt{2} + 1)$

Step-by-step explanation:

$\sqrt{2} x - 10 + x - 15 + 3 \sqrt{2} x - 15 = 180$

$2 \sqrt{2} x + x - 25 - 15 = 180$

$2 \sqrt{2} x + x - 40 = 180$

$2 \sqrt{2} x + x = 220$

$x = 220 \div (2 \sqrt{2} + 1)$

$x(2 \sqrt{2} + 1) = 220$
