5x +1 =11
2 . 5 + x: 5 − 3 = 9 + 3 Elevado a la 0

Answer 1

Respuesta:

x − 7 = 32

$x-7+7=32+7\\\\x=39$

x: 4 = 12

$\frac{x}{4}=12\\\\\frac{4x}{4}=12\cdot \:4\\\\x=48$

x + 6 = 15

$x+6-6=15-6\\\\x=9$

2 = 4x − 6

$4x-6=2\\\\4x-6+6=2+6\\\\4x=8\\\\\frac{4x}{4}=\frac{8}{4}\\\\x=2$

x + 8 = 22 + 7

$x+8=29\\\\x+8-8=29-8\\\\x=21$

22 − 3x = 4

$22-3x-22=4-22\\\\-3x=-18\\\\\frac{-3x}{-3}=\frac{-18}{-3}\\\\x=6$

28 − x = 8

$28-x-28=8-28\\\\-x=-20\\\\\frac{-x}{-1}=\frac{-20}{-1}\\\\x=20$

3x + 6 − 3 = 12 − 3

$3x+6-3+3=12-3+3\\\\3x+6=12\\\\3x+6-6=12-6\\\\3x=6\\\\\frac{3x}{3}=\frac{6}{3}\\\\x=2$

3x = 12

$\frac{3x}{3}=\frac{12}{3}\\\\x=4$

5x +1 =11

$\\\\x=2$

2 . 5 + x: 5 − 3 = 9 + 3 Elevado a la 0

$x=\frac{105}{2}$
