Solve with cross multiplication and eliminating method

4x+5y-23=0

2x+3y-13=0

---------------------------------------------------------

To find:

• answers of the equation by cross multiplication and eliminating method

---------------------------------------------------------

$\huge\mathfrak\red{A}\orange{N}\blue{S}\orange{W}\green{E}\pink{R}$

---------------------------------------------------------

$\boxed{\sf \green{★ \: By\: elimination\:method\: -}}$

$4x + 5y - 23 = 0 \\ 2x + 3y - 13 = 0$

$by \: bringing \: - 23 \: and \: - 13 \: on \: the \: right \: side \: we \: get$

$4x + 5y = 23 \\ 2x + 3y = 13$

$multiply \: 2x + 3y = 13 \: \: by \: \: 2$

$so \: that \: the \: first \: term \: e \: the \: same$

4x +5y=23.

the +4x and -4x will be cut by each other

4x+6y=26.

- - -

——————

-y =-3

y=3

now finding x

4x+5y=23

so , 4x+5(3)=23

4x=8

x=2.
