Question

Find the value of unknown variable in 5x  5= 2x + 7

Answer 1

Answer:

X = 9

Step-by-step explanation:

the equation is,

$5 \times 5 = 2x + 7$

so,

$5 \times 5 = 25$

we can say that,

$25 = 2x + 7$

therefore,

$25 - 7 = 2x$

by transposing 7 to L. H. S

$= 25 - 7 = 18$

$= \frac{18}{2} = x$

by transposing 2 to L. H. S
