Question

3x-7=3(5-x)
solve the linear equation​

Answer 1

Answer:

3x-7=3(5-x)

=3x-7=15-3x

3x+3x=15+7

6x=22

x=22/6

x=11/3

Answer 2

Step-by-step explanation:

3x-7 = (3×5)-(3×x)

3x-7 = 15-3x

3x+3x = 15+7

6x = 22

x = 22÷6

x = 11/3.

Check:

LHS = 3x-7 = (3×11/3)-7 = 11-7 = 4

RHS = 3(5-x) = 3(5-11/3) = 15-11 = 4.

Hence, LHS = RHS.

Therefore, x = 11/3.
