Question

Solve: 7 (x + 3) = 10x-3​

Answer 1

Answer:

the required solution of the given equation 7(x+3) = 10x-3 is x = 8

Step-by-step explanation:

given equation is 7(x+3) = 10x-3

7(x+3) = 10x-3

⇒ 7x + 21 = 10x - 3

⇒ 3 + 21 = 10x - 7x

⇒ 3x = 24

⇒ x = 24/3 = 8

then we get x = 8

therefore the required solution of the given equation 7(x+3) = 10x-3 is x = 8

now putting the value x = 8 in the L.H.S of the given equation we get ,

7 (8+3) = 7 × 11 = 77

now putting the value x = 8 in the R.H.S of the given equation we get ,

10 × 8 - 3 = 80 - 3 = 77

hence  L.H.S = R.H.S

therefore x = 8 satisfies the given equation
