I need help on math.<br>h(x)=8x-10<br>h( )=62

andriy [413]

Simplifying

8x + -10 = 62

Reorder the terms:

-10 + 8x = 62

Solving

-10 + 8x = 62

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 8x = 62 + 10

Combine like terms: -10 + 10 = 0

0 + 8x = 62 + 10

8x = 62 + 10

Combine like terms: 62 + 10 = 72

8x = 72

Divide each side by '8'.

x = 9

Simplifying

x = 9
