x + 2 = 3x + -1x2 + 5
Reorder the terms:
2 + x = 3x + -1x2 + 5
Reorder the terms:
2 + x = 5 + 3x + -1x2
Solving
2 + x = 5 + 3x + -1x2
Solving for variable 'x'.
Reorder the terms:
2 + -5 + x + -3x + x2 = 5 + 3x + -1x2 + -5 + -3x + x2
Combine like terms: 2 + -5 = -3
-3 + x + -3x + x2 = 5 + 3x + -1x2 + -5 + -3x + x2
Combine like terms: x + -3x = -2x
-3 + -2x + x2 = 5 + 3x + -1x2 + -5 + -3x + x2
Reorder the terms:
-3 + -2x + x2 = 5 + -5 + 3x + -3x + -1x2 + x2
Combine like terms: 5 + -5 = 0
-3 + -2x + x2 = 0 + 3x + -3x + -1x2 + x2
-3 + -2x + x2 = 3x + -3x + -1x2 + x2
Combine like terms: 3x + -3x = 0
-3 + -2x + x2 = 0 + -1x2 + x2
-3 + -2x + x2 = -1x2 + x2
Combine like terms: -1x2 + x2 = 0
-3 + -2x + x2 = 0
Factor a trinomial.
(-1 + -1x)(3 + -1x) = 0
Subproblem 1Set the factor '(-1 + -1x)' equal to zero and attempt to solve:
Simplifying
-1 + -1x = 0
Solving
-1 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + -1x = 0 + 1
Combine like terms: -1 + 1 = 0
0 + -1x = 0 + 1
-1x = 0 + 1
Combine like terms: 0 + 1 = 1
-1x = 1
Divide each side by '-1'.
x = -1
Simplifying
x = -1
Subproblem 2Set the factor '(3 + -1x)' equal to zero and attempt to solve:
Simplifying
3 + -1x = 0
Solving
3 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -1x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -1x = 0 + -3
-1x = 0 + -3
Combine like terms: 0 + -3 = -3
-1x = -3
Divide each side by '-1'.
x = 3
Simplifying
x = 3Solutionx = {-1, 3}</span>
Answer:
Step-by-step explanation:
Given:
(y/y - 4) - (4/y + 4) = 32/y^2 - 16
Note y^2 - 16 = (y - 4 ) × (y + 4)
Multiplying the equation; both sides by y^2 - 16,
y (y + 4) - (4(y - 4)) = 32
y^2 + 4y - 4y + 16 = 32
y^2 = 32 - 16
Squaring both sides,
y = sqrt(16)
= 4
Answer:
$120
Step-by-step explanation:
80%=$96
1%=80%/80=96/80=1.2
100%=1%×100%=1.2×100=120
