Five times a number decreased by 18 minus 4 times the same number is -36. what is the number?

kaheart [24]

(5x - 18) - 4x = -36

Let's solve your equation step-by-step.

5x − 18 − 4x = −36

Step 1: Simplify both sides of the equation.

5x − 18 − 4x = −36

5x + −18 + −4x = −36

(5x + −4x) + (−18) = −36 (Combine Like Terms):

x + −18 = −36

x − 18 = −36

Step 2: Add 18 to both sides.

x − 18 + 18 = −36 + 18

x = −18

Answer: ========> x = -18 is the number

Hope that helps!!!! : )

68 * 27 - 81 + ? = 600

tankabanditka [31]

The missing term is -1155.

Step-by-step explanation:

Given expression is

68 * 27 - 81 + ? = 600

Let the missing term be x

$68*27-81+x=600\\1836-81+x=600\\1755+x=600$

Subtracting 1755 from both sides

$1755-1755+x=600-1755\\x=-1155$

Therefore,

The missing term is -1155.
