Question

3x+4y=253, y=5x(hint:y=5x means y-5x=0.solve x and y​

Answer 1

Answer:

heya mate ☺

$3x + 4y = 253 \\ putting \: the \: value \: of \: y \\ = > 3x + 4(5x) = 253 \\ = > 3x + 20x = 253 \\ = > 23x = 253 \\ = > x = 253 \div 23 \\ = > x = 11$

$y = 5x \\ putting \: the \: value \: of \: x \\ = > y = 5(11) \\ = > y = 55$

Answer 2

Answer:

x=11 and y=55

Step-by-step explanation:

given,

y=5x...........(1)

substituting (1) in equation,

3x+4(5x)=253

3x+20x=253

23x=253

x=$\frac{253}{23}$

x=11...........(2)

substituting (2) in (1)

y=5(11)

y=55
