What number needs to be added to 5 and 3 so that the ratio of the first number to the second

Mashcka [7]

Answer:

Step-by-step explanation:

Choose a variable to represent the number to be added to 5 and 3.

$\frac{5+x}{3+x}=\frac{4}{3}$

"Cross-multiply."

$3(5+x)=4(3+x)\\\\15+3x=12+4x\\\\15=12+x\\\\3=x$

Check: The ratio of 5+3 to 3 + 3 is 8:6, equal to the ratio 4:3.

Y = 4x+2<br>y = -2x - 3

Dima020 [189]

Solve for x and y

y = 4x+2

y = -2x - 3

<h3><u>Answer:</u></h3>

$x = \frac{-5}{6}$ and $y = \frac{-4}{3}$

<h3><u>Solution:</u></h3>

Given equations are:

y = 4x+2 --------- eqn 1

y = -2x - 3 ---------- eqn 2

We have to solve both equations and find values of "x" and "y"

Substitute eqn 1 in eqn 2

4x + 2 = -2x - 3

Combine like terms we get,

4x + 2x = -3 - 2

On solving,

6x = -5

$x = \frac{-5}{6}$

Substitute "x" value in eqn 1

$y = 4(\frac{-5}{6}) + 2\\\\y = \frac{-20}{6} + 2\\\\y = \frac{-20 + 12}{6}\\\\y = \frac{-8}{6} = \frac{-4}{3}$

Thus $x = \frac{-5}{6}$ and $y = \frac{-4}{3}$
