Question

Solve the following equation
3n +7= 25
8t + 3 = 99
4 ( x + 3 ) = 26
6 ( p + 2 ) = - 18

Answer 1

Answer:

n=6,t=12,x=7/2,p= -5

Answer 2

Answer:

i) 3n+7=25

3n=25-7

3n=18

n=18/3

n=6

ii) 8t+3=99

8t=99-3

8t=96

t=96/8

t=12

iii) 4(x+3) =26

4x+12=26

4x=26-12

4x=14

x=14/4

x=3.5

iv) 6(p+2)= -18

6p+12= -18

6p= -18-12

6p= -30

p= -30/6

p= -5
