Question

Hello guys please give me answer .
in step by step instructions.
please guys​

Answer 1

Answer:

(3+4x) × 3 = (7-5x) × -11

9+12x = -77+55x

9+77 = 55x-12x

86 = 43x

x = 86/43

x = 2

3+4x/7-5x = -11/3

3+4×2/7-5×2 = -11/3

3+8/7-10 = -11/3

11/-3 = -11/3

i.e.-11/3 = -11/3

Answer 2

Step-by-step explanation:

Given:-

(3+4x)/(7-5x) = (-11/3)

To find:-

Solve (3+4x)/(7-5x) = (-11/3)

Solution:-

Given equation is (3+4x)/(7-5x) = (-11/3)

On applying cross multiplication then

=>(7-5x)(-11) = (3+4x)(3)

=>( 7× -11)-(5x × -11) = (3×3) + (4x×3)

=>-77 -(-55x) = 9 + (12x)

=>-77 + 55x = 12x +9

=>55x -12x = 9+77

=>43x = 86

=>x = 86/43

=>x = 2

The value of x = 2

Answer:-

The solution for the given problem is 2

Check:-

The value of x =2

Now LHS in the given equation

(3+4x)/(7-5x)

On Substituting the value of x then

=>[3+4(2)]/[7-5(2)]

=>(3+8)/(7-10)

=>11/-3

=> -11/3

=>RHS

LHS = RHS is true for x=2 for the given problem
