∙ 14y agou work backwards. u start with ur answer, -10. then u add 5 instead of subtracting. ur problem then becomes -10+5. the answer being -5.
working backwards is the simplest method of algebra.

How do you solve x5?
x5 is an expression, not an equation nor an inequality. An expression cannot be solved.
How do you solve the proportion x5 equals 1610?
Assuming that the question is find x in x5=1610; the answer is 4.378901
State the degree of the polynomial equation x to the 5th power plus 7x cubed minus 30x equals 0?
For the equation: x5+7x3-30x=0 The highest exponent in the entire equation is 5 (from x5), so the equation is of degree 5.
How do you solve x5 equals 64x2?
x5 = x3 times x2. In this case x3 = 64 so x = cube root of 64 ie 4
If the value of x in the equation 4x5 equals 3 is half the value of x in the equation kx plus 10 equals 2 then what is the value of k?
Assume that the expression 4x5 in the question is 4x5.4x5 = 3 : x5 = 3/4 : x = 5√(3/4) : then 2k.5√(3/4) + 10 = 2 : 2k.5√(3/4) = 2 - 10 = -8 :k = -4 ÷ 5√(3/4) = -4 ÷ 0.9441 = -4.2369 (4dp)

Ax5 plus bx5 plus cx5 plus dx5 plus ex5 equals abcde what is abcde?
a(x5) + b(x5) + c(x5) + d(x5) + e(x5) = abcde(a+b+c+d+e) x5 = abcdeThis equation has at least 5 variables. To solve for all of them requires at least 4 more equations.

How do you solve x - x x?
x10 = x5.x5 = (x5)2 [x power five whole squared] Equation is x10 + x5 - 2 Replacing x10 (x5)2+x5 - 2 Substituting x5 by Y Equation becomes Y2 + Y - 2 = 0 Y2 + 2Y - Y - 2 = 0 Y(Y + 2) - 1(Y+2) = 0 (Y-1)(Y+2) = 0 The values of Y are 1 and -2 Y = x5 = 1 Therefore, x = 1 Y = x5 = -2 x = fifth root of -2, which is an imaginary value.
What is the equation for y-x5?
y-x5 is an expression. An expression is not equivalent to any equation.
What is 1565 equals x5?
1,565 = x5 1,5651/5 = (x5)1/5 1,5651/5 = x5/5 1,5651/5 = x 4.3541 = x
What x5 equals 55?
11x5=55 !
If the value of x in the equation 4x5 equals 3 is half the value of x in the equation kx plus 10 equals 2 then what is the value of k?
Assume that the expression 4x5 in the question is 4x5.4x5 = 3 : x5 = 3/4 : x = 5√(3/4) : then 2k.5√(3/4) + 10 = 2 : 2k.5√(3/4) = 2 - 10 = -8 :k = -4 ÷ 5√(3/4) = -4 ÷ 0.9441 = -4.2369 (4dp)
What does 512 x5 equals?
512 x 5 = 2,560
What is 5x -9 when x equals 4?
5x-9Substitute 4 in for x5(4)-9=Solve.9-9=0the answer is zero.The answer is not zero you added when you were supposed to multiply so the real answer is 11.
