Question

Me ayudan es para hoy, tengo que resolver 10, 12, 15, 20, 22, 25 y 26​

Answer 1

Respuesta:

$10) \: 3x + 15 = 5x - 15 \\ 30 = 2x \\ 15 = x$

$12) \: x + 73 = 7x - 5 \\ 78 = 6x \\ 13 = x$

$15) \: 3x + 10 = 5x - 50 \\ 60 = 2x \\ 30 = x$

$20) \: 2x + 20 + 3x - 40 = 180 \\ 5x - 20 = 180 \\ 5x = 200 \\ x = 40$

$22) \: x = 62$

$25) \: A + B + C + D + 65 + 56 = 360 \\ A = 56 \\ B = D \\ C = 65 \\ 56 + 65 + B + B + 65 + 56 = 360 \\ 242 + 2B = 360 \\ 2B = 118 \\ B = 59$

$26) \: A + B + C + D + 86 + 18 = 360 \\A = D \\ C = 18 \\ B = 86 \\ A + 86 + 18 +A + 86 + 18 = 360 \\ 2A + 208 = 360 \\ 2A = 152 \\ A = 76$
