Question

X-4.6y=-9.8
-X+4.8y=10.4

Answer 1

x = 4

y = 3

Explanation:

x - 4.6y = -9.8

-x + 4.8y = 10.4

multiply both equations by 5 to remove the decimals in the variables.

we then get this:

5x - 23y = -49

-5x + 24y = 52

multiply one of the equations by -1 to get this

-5x + 23y = 49

-5x + 24y = 52

now subtract the equations

0x -y = -3

y = 3

plug back into equation to get value of x

x - 4.6(3) = -9.8

x - 13.8 = -9.8

x = 4
