That equation has no solution. There is no possible number that's equal to 18 more than itself.
5x * 18 = 201. /185x=1.111111112. /5x=0.2222222222
5x-19 = 16 5x = 16+19 5x = 35 x = 7
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
x=7
That equation has no solution. There is no possible number that's equal to 18 more than itself.
5x-y equals 18 = -13
To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x. 5x - 4(0) = 18 5x = 18 x = 18/5 or 3.6 The line will hit the x-axis at (3.6,0)
Let y = 0, and solve for x. 5x - 4(0) = 18 5x = 18 divide by 5 both sides x = 18/5 (the x-intercept) Thus, the x-intercept point is (18/5, 0).
5x * 18 = 201. /185x=1.111111112. /5x=0.2222222222

Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
5x-19 = 16 5x = 16+19 5x = 35 x = 7
5x = 25Divide both sides by 5:x = 5
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
