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

Answer: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: Answer:  {x = 8/5 , y = -1.6
