What is the simultanous equation of 2x+y=–5 3x+2y=–8 equation Using the Substitution method

Artyom0805 [142]

Answer: Equation $form:$ $x=-2,y=-1$

$Point$ $form:$ $(-2, -1)$

Step-by-step explanation:

$y=-\frac{3x}{2} -4$

$y=-2x-5$

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

$Solve$ $by$ $Substitution$ ---> $2x+y=-5 3x+2y=-8$

There were 60 ducks living in a pond. If the number living at the pond increased by 30%, how many ducks now live at the pond?

timama [110]

Answer:

Step-by-step explanation:

You take the original total: 60, and multiply it by 30 to get 1,800. You then divide 1,800 by 100 to get 18. 18 is your 30%. Now, you add the 30% to 60 getting your total number of ducks: 78.

The equation version:

$\frac{a}{60} = \frac{30}{100}$

It is just proportions.
