Multiply the bottom equation by -1

3x = 24, x = 8

If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52

When 5x+3 = 17 then x = 2.8 Therefore when 8x-y = 3 then x = 2.8 and y = 19.4

9x + 5 = 5x + 179x + 5 - 5x = 179x - 5x = 4x5-4x=1717-5=1212 divided by 4 = 3x=3

Multiply the bottom equation by -1

5x + 3y = 17 is in its simplest form because there are no alike terms to combine.

(1, 4)

3x = 24, x = 8

If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52

3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
