Answer 1

Step-by-step explanation:

first x= 4+5=9

x=2 multiple 3 = 6

now 9-6= 3

answer 6

Answer 2

Answer:

$\frac{x}{4} + 5 = \frac{2x}{3} \\cross \: multiply \:L.H.S\\ \frac{x + 20}{4} = \frac{2x}{3}$

Cross multiply both sides

$3(x + 20) = 4(2x) \\ 3x + 60 = 8x$

cancelling 3x from both sides

that is

$60 = 5x \\ x = 60 \div 5 \\ x = 12$

therefore the value of x=12

Therefore the correct answer is

Option A) 12

Let's check whether it's correct or not

$\frac{x}{4} + 5 = \frac{2x}{3} \\ \frac{12}{4} + 5 = \frac{2 \times 12}{3} \\ 3 + 5 = \frac{24}{3} \\ 8 = 8$

L.H.S=R.H.S

hence verified
