T + 5 + 3T = 1
Simplify the terms, T and 3T (think 1 apple plus 3 apples)
4T + 5 = 1
Subtract 5 from both sides.
4T = -4
then divide both sides by 4 to get T by itself.
T = -4/4
T = -1
To check, substitute T = -1 wherever you see T in your original equation.
T + 5 + 3T = 1
(-1) + 5 + 3(-1) = 1
4 - 3 = 1
1 = 1 (check)

How do you solve the equation 3x-12 plus 4x plus 7?
Without an equality sign it's not an equation but it can be simplified to: 7x-5
What is the equation of the midline of the graph of y equals 4cos3x plus 6?
y=6
What is the value of sin2θ plus cos2θ?
sin2θ + cos2θ = 1
What is the answer to 35x to the second plus 34x plus 8 when factoring?
Presumably this is a quadratic equation question in the form of 35x2+34x+8 = 0 35x2+34x+8 = 0 (7x+4)(5x+2) = 0 Answer: x = -7/4 or x = -2/5 Usually you can factorise a quadratic equation by trial and improvement but in this case it's quicker to use the quadratic equation formula.
What is the value of sin 20degrees-cos70degrees plus sec30degrees-cosec60degrees?
It is 0.
What does y equal in this equation y equals 2x plus 4?
As the equation plainly tells us, "Wye is equal to two eks plus four". The value of 'y' completely depends on the value of 'x'. Whenever 'x' changes, the value of (2x + 4) changes instantly.
What does w equal in this equation 105 plus 13w?
There is no equation, just an expression. And, since it is an expression, it cannot be solved so w can equal any value whatsoever.
How do you find x value in this equation 5x3 plus 3x2-30x-18?
With difficulty because it's not an equation but an expression.
Find the value of x in the equation x plus 5 equals x plus 45?
There is no numerical value for 'x' that can make this a true statement.
What does x and y equal and the equation for x for 2x plus 5 equals 62 and 3x - y equals 23.3?
2x+5 = 62 and 3x-y = 23.3 x = 28.5 and y = 62.2 Solve the first equation and then substitute the value of x into the second equation to find the value of y.
-2x plus 4y -4 find the y?
The value of y in the equation -2x plus 4y -4, is 1 plus x/2.
What is the value of k when the equation x squared plus 2kx plus 10x plus k squared plus 5 equals 0 has equal roots?
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
What is the value of the discriminant for the equation 21 plus 33 plus 4?
There is no variable, and the equation is not valid.
What does -7x plus 7 plus -5x plus 3 plus 74x-2 equals?
you need to find the value of X first before you can solve this equation
3x plus 6y equals 48 -5x plus 6y equals 32?
Presumably this is a simultaneous equation question in the form of: 3x+6y = 48 -5x+6y = 32 Subtract the bottom equation from the top equation in order to eliminate y. Note that 3x - - 5x is equal to + 8x: 8x = 16 Divide both sides by 8 to find the value of x: x = 2 Substitute the value of x into the original equations to find the value y: Therefore: x = 2 and y = 7
The vertex form of the equation of a parabola is y x-5 2 plus 16 what is the standard form of the equation?
In the equation y x-5 2 plus 16 the standard form of the equation is 13. You find the answer to this by finding the value of X.
Solve this equation -9h - 6 plus 12h plus 40 equals 22?
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
