What is the solution to the system of equations? y = 1.5x – 4 y = –x (–1.6, 1.6) (–1.5, 1.5) (1.5, –1.5) (1.6, –1.6)

x = 1.6 , y = -1.6 or your Answer (1.6, –1.6)

Step-by-step explanation:

Substitute y = 1.5 x - 4 into the second equation:

{y = 1.5 x - 4

1.5 x - 4 = -x

In the second equation, look to solve for x:

{y = 1.5 x - 4

{1.5 x - 4 = -x

1.5 x - 4 = (3 x)/2 - 4:

{(3 x)/2 - 4 = -x

Add x + 4 to both sides:

{y = 1.5 x - 4

{(5 x)/2 = 4

Multiply both sides by 2/5:

{y = 1.5 x - 4

{x = 8/5

Substitute x = 8/5 into the first equation:

{y = -1.6

{x = 8/5

Collect results in alphabetical order:

 {x = 8/5 , y = -1.6

41*67/2=1373.5
