Multiply the bottom equation by -1
If x equals 7 and y equals 2x plus 3 what is 5x plus y?
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
What is 5x plus 17 equals 2x plus 41?
3x = 24, x = 8
8x-y equals 4 5x plus 3 equals 17?
When 5x+3 = 17 then x = 2.8 Therefore when 8x-y = 3 then x = 2.8 and y = 19.4
What is 9x plus 5 equals 5x plus 17?
9x + 5 = 5x + 179x + 5 - 5x = 179x - 5x = 4x5-4x=1717-5=1212 divided by 4 = 3x=3
