You can't answer this question without setting that expression equal to something. Right now, your equation reads 4x+15=?, essentially created a system of two variables with only one equation, which is unsolvable.

What is the solution to the equation below 4x equals x plus 15?
If: 4x = x+15 Then: x = 5
How do you solve y equals 2x plus 15 and y equals 4x plus 7 using substitution?
y = 2x + 15 y = 4x + 7 Substitute the value of y from the first equation into the second: 2x + 15 = 4x + 7 Subtract 2x from both sides: 15 = 2x + 7 Subtract 7 from both sides: 8 = 2x Divide both sides by 2: 4 = x. Replace x by its value, 4, in the first equation: y = 2*4 + 15 = 8 + 15 = 23 So the solution is (x, y) = (4, 23)
What is 3x plus 5 equals 4x-10?
3x+5= 4x-10+10 +103x+15= 4x-3x -3x15=X
4x - 7 equals -15 what is x?
4x - 7 = -15 4x = -8 x = -2
What is x2 plus 4x plus 3 factorised?
x2 + 4x + 3 = (x + 1)(x + 3)
-10 plus 4x 50?

What is the answer to -15-11?
If you mean 6(x-11) = 15-4x then 6x-66 = 15-4x and the value of x works out as 8.1
How do you solve 4x plus 7-3x equals 15?
4x+7-3x = 15 4x-3x = 15-7 x = 8
What is the substiution eqaution for x plus y equals 15 and 4x plus 3y equals 38?
x + y = 154x + 3y = 38from the first equation, y = 15-xsubstitute this value in the second equation as follows:4x + 3(15-x)= 384x + 45 - 3x = 38x + 45 = 38x = 38 - 45so, x = -7substitute this value to solve for y:y = 15 -xy = 15-(-7)y = 22
