Question

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 1

y = 1.5x - 4 = -x
1.5x + x = 4
2.5x = 4
x = 1.6
y = -1.6
Solution is (1.6, -1.6)

Answer 2

The solution to the system of equations y = 1.5x - 4 and y = -x  is (1.6,-1.6)

How to determine the solution?

The equations are given as:

y = 1.5x - 4

y = -x

Substitute y = -x in the first equation

-x = 1.5x - 4

Collect like terms

-1.5x - x = -4

This gives

-2.5x = -4

Divide both sides by -2.5

x = 1.6

Substitute x = 1.6 in y = -x

y = -1.6

Hence, the solution to the system of equations is (1.6,-1.6)
