12x - 5 = 8x - x + 50 Help please show work and check the solution

Inga [223]

Answer:

x = 11

Step-by-step explanation:

$12x - 5 = 8x - x + 50 \\ 12x - 5 = 7x + 50 \\ 12x - 5 - 7x = 7x + 50 - 7x \\ 12x - 7x - 5 = 50 \\ 5x - 5 = 50 \\ 5x - 5 + 5 = 50 + 5 \\ 5x = 55 \\ x = 11$

and check:

$12(11) - 5 = 8(11) - (11) + 50 \\ 132 - 5 = 77 + 50 \\ 127 = 127$

The graphs of the equations $y=3x-20$ and $y=-2x+10$ intersect at the point $(6,-2)$. Without solving, find the solution of the

Maru [420]

Answer:

The solution is

$\boxed{x=6,y=-2}$

Step-by-step explanation:

The given equations are

$y=3x-20$

and

$y=-2x+10$

The graph of the two equations intersects at $(6,-2)$ as show in the graph in the attachment.

The point of intersection of the two graphs is the solution to system of equations.

Hence the solution is

$x=6,y=-2$
