Answer:

x=-9

Step-by-step explanation:

STEP 1: Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

$9(x-5)-14x=-7(x+9)$

STEP 2: Simplify 9(x−5)−14x.

$-5x-45=-7(x+9)$

STEP 3: Simplify −7(x+9).

$-5x-45=-7x-63$

STEP 4: Move all terms containing x to the left side of the equation.

$2x-45=-63$

STEP 5: Move all terms not containing x to the right side of the equation.

$2x=-18$

STEP 6: Divide each term by 2 and simplify.

$x=-9$

vredina [299]

Answer:

Step-by-step explanation:

From the given table,

To prepare a mixture of a paint, two paints of different shades have been added in the same ratio,

Since, 2 cups of blue paint are mixed with 10 cups of yellow paint

Therefore, ratio in which these shades have been added = $\frac{\text{Pink}}{\text{Blue}}$

= $\frac{10}{2}$

= $\frac{5}{1}$

= 5 : 1

For 1 cup of blue paint number of cups of yellow paint required,

$\frac{x}{1}=\frac{5}{1}$

x = 5 cups

For 3 cup of blue paint number of cups of yellow paint required,

$\frac{x}{3}=\frac{5}{1}$

x = 15 cups

Cups of blue paint Cups of yellow paint
