y - 1

Subtracting y = x + 1 from y = 2x - 1 gives 0 = x - 2; whence, x = 2, which is your answer.

x = 3 y = 4 2x + y - 1 = (6) + (4) - 1 = 9

x = -1/3 and y = 7/12

If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.

If you mean: y = 3x+1 then the value of y will equal 10

x=1y=2x+3y=2*1 + 3y=5

y = 2x+5 x+y = 4 Substitute the value of y into the second equation: x+2x+5 = 4 x+2x = 4-5 3x = -1 Divide both sides by 3 to find the value of x: x = -1/3 Substitute the value of x into the original equations to find the value of y: x = -1/3 and y = 4 and 1/3

here for least value X=2,y=3hence 2(3)-3(2)=0=0
