What is the solution to this equation 4x plus 10 plus 3x equals 40 minus 3x?
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
Use addition or substitution to find the value of y for this set of equations 4x plus 13y equals 40 4x plus 3y equals -40?
a) 4x+13y=40 b) 4x+3y=-40c) multiply b per(-1)=-4x-3y-40d) sum a and c: 4x+13y-4x-3y=40-(-40)=>10y=80 => y=8to find x replace y per its value in a or b and get x=-16
Use addition or substitution to find the value of x for this set of equations 4x plus 13y equals 40 4x plus 3y equals -40?
Try elimination.4X + 13Y = 40- 1(4X + 3Y = - 40)4X + 13Y = 40- 4X - 3Y = 40-----------------------add10Y = 80Y = 8-------------find X ( top equation )4X + 13(8) = 404X + 104 = 404X = - 64X = - 16----------------------check in both equations for consistency4(- 16) + 13(8) = 40- 64 + 104 = 4040 = 40-------------top checks4(- 16) + 3(8) = - 40- 64 + 24 = - 40- 40 = - 40-------------------both check and are consistentSo, X is,- 16 ( while Y is 8 )
Find the solutions for 4x squared plus 4x plus 1 equals 0?
x = -½
Does 4x plus 4x equals 8x?
Only if 4 dollars plus 4 dollars equals 8 dollars.And if you had another 4x, you'd have a dozen-x.
What is the solution to this equation 4x plus 10 plus 3x equals 40 minus 3x?
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
You write 4x plus 4y equals 40?
How do you write 4x plus 4y equals 40 or how do you solve it? You would write it 4x+4y=40 you would solve it for y by subtracting 4x from both sides 4y=40-4x then divide all of that by 4y=40-4x/4 that's if you were graphing i have no idea what you're asking hope that helps if it's not too late.
What is x if x plus 3x equals 40?

4x plus 32 equals -4x plus 16 x equals?
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
What is the equation for -4x plus 4y equals plus 1?
-4x + 4y = 1
Solve by the substitution method 4x-5y equals -8 4x plus 40 equals y?
4x-5y = -8 4x+40 = y => y = 4x+40 Substitute the value of y into the top equation: 4x-5(4x+40) = -8 4x-20x-200 = -8 4x-20x = 200-8 -16x = 192 Divide both sides by -16 to find the value of x: x = -12 Substitute the value of x into the original equations to find the value of y: Therefore: x = -12 and y = -8
