Question

Solve for x please! Thanks

Answer 1

take the squar root of both sides and remember the positive and negative roots
remember
`\sqrt{ (x)/(y) } = ( √(x) )/( √(y) )`
so

`x^2= (49 )/(121 )`
square root both sides

`x= \sqrt{ (49)/(121) } = ( √(49) )/( √(121) )= +/-( 7 )/( 11 )`


x=-7/11 or 7/11
