Question

-7t=3t-30 solve the equation and prove LHS RHS

Answer 1

-7t = 3t -30

-7t - 3t =- 30

-10t =- 30

t = -30/-10

t=3

-7(3)=3(3)-30

-21=9-30

-21=-21

therefore,

LHS=RHS

Answer 2

Answer:

1)t=7.4

2)LHS=RHS is proved.

Step-by-step explanation:

→-7t=3t-30

→-7t-3t=-30

→-4t=30

→4t =30

→t=30/4

→t=7.4

→proof=

→-7t=3t-30

we found t =7.4

so,

→-7(7.4)=3(7.4)-30

→-51.8=-22.2-30

→-51.8=-51.8

→hence, LHS =RHS is proved.
