¿Cuál es el resultado de restar la segunda ecuación de la primera? \ begin {alineado} 2x + 7y & = -8 2x-5y & = -1 \ end {alineado} 2 x+7 y 2 x-5 y =- 8 =- 1

understand that i don't know the answers

will someone answer his question

just pick what you think i need more time let me know if this

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
