Question

solve using trial and error method a. 2x=16 b. 3x+7=16 c. 4x/3=4 d. 5x+12=17 e. 2x+5=15​

Answer 1

Answers :

a. 2x = 16

x = $\frac{16}{2}$ = 8

b. 3x + 7 = 16

3x = 16 - 7 = 9

x = $\frac{9}{3}$ = 3

c. $\frac{4x}{3}$ = 4

4x = 4*3 = 12

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

d.  5x+12=17

5x = 17 - 12 = 5

x = $\frac{5}{5}$ = 1

e. 2x+5=15​

2x = 15 - 5 = 10

x = $\frac{10}{2}$ = 5

∴ a. 8, b.3, c. 3, d. 1, e. 5.
