Question

Solve the equation 7/y-12=3/y+4

Answer 1

Answer:

transposing

we get

7/y-3/y= 16

4/y=16

16y=4

y=4/16

y= 1/4

Answer 2

Given:-

•Equation↓

=>$\frac{7}{y}$-12=$\frac{3}{y}$+4

$\rule{200}{1}$

To Find:-

๛Find the value of y?

$\rule{200}{1}$

AnsWer:-

♦Cross Multiply in Both LHS&RHS♦

→$\frac{7-12y}{y}$=$\frac{3+4y}{y}$

→$\frac{7-12y-(3+4y)}{y}$=0

→$\frac{7-12y-3+4y}{y}$=0

•Transposing y to RHS•

→4-8y=0×y

→4-8y=0

→-8y=-4

→y=$\frac{\cancel{-4}}{\cancel{-8}}$

→y=$\frac{1}{2}$

$\rule{200}{2}$
