# How do you solve 8x^2+ 7 = 9x^2+ 10?

Nov 9, 2015

$8 {x}^{2} + 7 = 9 {x}^{2} + 10$
$8 {x}^{2} - 9 {x}^{2} = 10 - 7$
$- {x}^{2} = 3$
${x}^{2} = - 3$
$x = \sqrt{3}$

#### Explanation:

first, you separate and move the number to the other side and ${x}^{2}$ to the other side.

then solve it.
${x}^{2}$ when we bring to the other side will become square root.
