Examine this system of equations. Which numbers can be multiplied by each equation so that when the two equations are added toge

Karolina [17]

The first equation must be multiplied by 18 and second equation must be multiplied by 8

Solution:

Given system of equations are:

$\frac{1}{4}x -\frac{1}{6}y = 5$ --------- eqn 1

$\frac{4}{5}x +\frac{3}{8}y = 10$ -------------- eqn 2

Multiply the second equation by 8 both sides to remove the fraction in the variable y

$8(\frac{4}{5}x +\frac{3}{8}y = 10)\\\\\frac{32x}{5} + 3y = 80 -------- eqn 3$

Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y

$18(\frac{1}{4}x -\frac{1}{6}y = 5)\\\\\frac{18}{4}x -3y = 90 ---------- eqn 4$

Add eqn 3 and eqn 4

$\frac{32}{5}x +3y +\frac{18}{4}x -3y = 80+90\\\\\frac{32}{5}x+\frac{18}{4}x = 170$

Thus the y-term is eliminated

Therefore, first equation must be multiplied by 18 and second equation must be multiplied by 8

Find the slope and the y-intercept of the of the linear equation. 0=2-3y+12x

andrew11 [14]

The slope is 4 and the y-intercept is $\frac{2}{3}$

Step-by-step explanation:

The general form of a linear equation is Ax + By + C = 0, where

A is the coefficient of x
B is the coefficient of y
C is the numerical term
A, B, and C are integers
The slope of the line = $\frac{-A}{B}$
The y-intercept = $\frac{-C}{B}$

∵ The linear equation is 0 = 2 - 3y + 12x

- Switch the two sides and arrange the terms as the general

form above

∴ 12x - 3y + 3 = 0

∴ A = 12

∴ B = -3

∴ C = 2

∵ The slope of the line = $\frac{-A}{B}$

- Substitute A by 12 and B by -3

∴ The slope of the line = $\frac{-12}{-3}$

∴ The slope of the line = 4

∵ The y-intercept = $\frac{-C}{B}$

- Substitute C by 2 and B by -3

∴ The y-intercept = $\frac{-2}{-3}$

∴ The y-intercept = $\frac{2}{3}$

The slope is 4 and the y-intercept is $\frac{2}{3}$
