If: 4x = x+15 Then: x = 5
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)
3x+5= 4x-10+10 +103x+15= 4x-3x -3x15=X
4x - 7 = -15 4x = -8 x = -2
x2 + 4x + 3 = (x + 1)(x + 3)
The value of x in the equation -10+4x = 50 is 15
If: 4x = x+15 Then: x = 5
4x + 17 = x + 2 4x - x = 2 - 17 3x = -15 x = -5
If you mean 6(x-11) = 15-4x then 6x-66 = 15-4x and the value of x works out as 8.1
3x + 5 = 4x - 10Add 10 to each side:3x + 15 = 4xSubtract 3x from each side:15 = x
It is -x -15.
The value of x in the equation -2 x plus 3 4x-3 is 3.
The value of x is the unknown variable and the given expression can be simplified to: 4x-15
If you mean 5x+4x = 54 then the value of x is 6
If you mean 6(x-11) = 15-4x then 6x-66 = 15-4x and the value of x works out as 8.1
4x+7-3x = 15 4x-3x = 15-7 x = 8
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
