The point-slope form of the equation of a line is

$y - y_1 = m(x - x_1)$

where (x1, y1) is a point on the line, and m is the slope of the line.

$y - 3 = \dfrac{5}{3}(x - 0)$

$y - 3 = \dfrac{5}{3}x$

Multiply each equation by a constant that would help to eliminate the y terms.

Zinaida [17]

Answer:

Therefore the required resulting equation is

$6x-15y=-63\\-15x+15y=90$

6 x minus 15 y = negative 63.

Negative 15 x + 15 y = 90

Step-by-step explanation:

Given:

$2x-5y=-21$ ......................Equation ( 1 )

$3x-3y=-18$ ......................Equation ( 2 )

To Find:

Expression after multiplying to eliminate y term,

Solution:

So to eliminate 'y' term we need to multiply equation 1 by a constant 3 and equation 2 by a constant -5, such that equations becomes

$3(2x-5y)=3\times -21\\\\6x-15y=-63$ .....( 1 )

$-5(3x-3y)=-5\times -18\\\\-15x+15y=90$ .....( 2 )

so now by adding new equation one and two we can eliminate y term that means -15y and +15y will get cancel,

Therefore the required resulting equation is

$6x-15y=-63\\-15x+15y=90$

6 x minus 15 y = negative 63.

Negative 15 x + 15 y = 90
