**Answer:**

Hope it will be helpful.

**Step-by-step explanation:**

So, we can write 3x+7=7x+5

Simplify..3x-7x=5-7 or we can write 7x-3x=7-5

So, 4x=2

Which gives..x=1/2

Now putting value of x we get, 3x+7=x^2+m

3×1/2+7 =(1/2)^2+m

m=3/2+7-1/4

Hence the value of m=33/4 always verify with putting value of m into tge equation and confirm the answer.

Thank you!

We have,

3x + 7 = 7x + 5.

⇒ 4x = 2

⇒ x = 1/2 = 0.5

We also know,

3x + 7 = x2 + M

⇒ 3 × 0.5 + 7 – (0.5)2 = M

⇒ M = 1.5 + 7 - 0.25 = 8.25

120% of M will be = (120/100) × 8.25 = 9.9
