Question

Determine the value of x that makes each equation true.

Answer 1

#1

$\\ \sf\bull\longmapsto x+2=1$

$\\ \sf\bull\longmapsto x=1-2$

$\\ \sf\bull\longmapsto x=-1$

#2

$\\ \sf\bull\longmapsto 2x=1$

$\\ \sf\bull\longmapsto x=\dfrac{1}{2}$

#3

$\\ \sf\bull\longmapsto \dfrac{1}{7}x=1$

$\\ \sf\bull\longmapsto x=7$

#4

$\\ \sf\bull\longmapsto 11x=1$

$\\ \sf\bull\longmapsto x=\dfrac{1}{11}$

Answer 2

Answer:

$1) \: \: x = - 1 \\ \\ 2)\: \: \frac{1}{2} \\ \\ 3) \: x = 7 \\ \\ 4) \frac{1}{11}$

Step-by-step explanation:

$2 + x = 1 \\ x = 1 - 2 = - 1$

__o___o___

$2x = 1 \\ \\ x = \frac{1}{2}$

___o___o___

$\frac{1}{7} x = 1 \\ \\ x= 1 \div \frac{1}{7} \\ \\ x = 1 \times 7 \\ x = 7$

___o___o___

$x11 = 1 \\ 11x = 1 \\ \\ x = \frac{1}{11}$
