Alvin’s first step in solving the given system of equations is to multiply the first equation by 2 and the second equation by –3. which linear combination of alvin’s system of equations reveals the number of solutions to the system? 9x + 4y = 36 6x + 2.5y = 24 infinite solutions: 0x – 0y = 0 no solutions: 0x + 15.5y = 144 one solution: 0x + 0.5y = 0 two solutions: 0x – 0.5y = 60

30

step-by-step explanation:

times by times

answer: (-6,3)

step-by-step explanation:

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.
