Simplify the mathematical expressions to determine the product or quotient in scientific notation. Round so the first factor goes to the hundredths place. (4.5x104).(6.8x10–8) (2.8x102) (6.5x10-?) (5.6 x 10-3). (7.7 X 10-9) (8 x 10-2). (3.5 x 10-6) (7.4 x 10-5). (3.8 x 103) (9.3 x 10-4). (3.2 x 105) 1.82x10-4 → 3.06x10-3 9.45x10-4 1.54x10-4​

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

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

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
