if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3
If: 5x+2y = 9 Then: y = -2.5x+4.5 in slope intercept form
5x-3=37 (Original Equation) 5x=40(Add 3 to the right side) x=8(Divide 40 by 5)
(1) 5x+y=-12 (2) 7x-3y=-30 From (1) one gets y = -12-5x Put into (2) 7x-3y = 7x -3 (-12-5x) = 7x + 36 +15 x = 22x +36=-30 22x = -30-36 = -66 so x = -3 and y=-12-5x = -12-5x-3= 3 The solution is (-3,3)
5x - 7y = 5 (subtract both sides by 5x) -7y = -5x + 5 (divide both sides by -7) y = (5x - 5)/7 If you want to solve for y = 0, then x = 1.
No. x=3. (5x3 is 15 or 5x =15-3=12)
x = -5
5x-2=13 +2 +2 5x=15 x=3
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.
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
5x-3 = 37 5x = 37+3 5x = 40 x = 8
Oh, what a happy little equation we have here! When we have 4x equals 5x, we simply need to remember that both sides should be equal. So, if we subtract 4x from both sides, we get x equals 0. It's all about finding that balance and making sure both sides of the equation are in harmony.
5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
a linear equation solution 5x-37=13 5x=13+37 5x=50 x=10
This cannot be solved. It needs 2 equations to solve for 2 unknowns.
5x+25=10 5x+25-25=10-25 5x=-15 5x/5=-15/5 x=-3
No solution
