![x - 32 = 55 \\ + 32 \: + 32 \\ x = 87](https://img.qammunity.org/2022/formulas/mathematics/high-school/mrbvf1cmzq3kk3bylxzsdpl9hm20v2wju2.png)
![3x = 54 \\ / 3 \: / 3 \\ x = 18](https://img.qammunity.org/2022/formulas/mathematics/high-school/c8l5wn04azv64yktfsei9iqfai5bxz5l1g.png)
![(x)/(5) = 10 \\ (x)/(5) * 5 = 10 * 5 \\ \\ x = 50](https://img.qammunity.org/2022/formulas/mathematics/high-school/g9rv0rieubbnmmzej363xgkxr70copfw7s.png)
Explanation:
a) you have to minus 8 both sides of the equation, then found the answer
b)you have to add 32 both sides of the equation, and then found the value of x
c) divided by 3 both sides
d) multiply by 5 both sides
that is the way where you can find the value of x
