POSSIBLE POINTS: 1.11 An artist paints 1,053 stars on a ceiling. Each star has 7 points. Which expression can be used to find the total number of points on the stars?
O (1 + 50 + 3) x 7
O (1x 7) + (0 x 7) + (5 x 7) + (3x7)
O (1.000 x 7) + (500 x 7) + (3 x 7)
O (1,000 x 7) + (0 x 7) + (50 x 7) + (3 x 7)
How do I do this

y=mx+

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
