QveST [7]

$= \tt8x + 12 = -3x + 3 + 31$

$=\tt 8x + 12 + 3x = 3 + 31$

$= \tt11x + 12 = 34$

$= \tt11x = 34 - 12$

$= \tt11x = 22$

$=\tt x = \frac{22}{11}$

$\hookrightarrow\color{plum}\tt x = 2$

Thus, the value of x = 2

Let us check whether or not we have found out the correct value of x, by placing 2 in the place of x :

$=\tt 8 \times 2 + 12 = - 3 \times 2 + 3 + 31$

$= \tt16 + 12 = - 6 + 34$

$= \tt28 = 28$

Since the Left Hand Side and the Right Hand Side of the equation are equivalent, we can conclude that we have found out the correct value of x.

▪︎Therefore, the value of <u>x = 2</u>

Find the value of x.

Artemon [7]

${5}^{2} + {x}^{2} = {8}^{2}$

$25 + {x}^{2} = 64$

Subtract both sides 25

$25 - 25 + {x}^{2} = 64 - 25$

${x}^{2} = 39$

Thus :

$x = \sqrt{39}$

$x = 6.245$
