x-6-x-4=10-x
-10=10-x
-20=-x
x=20
check: 20-6-20-4=10-20
-10=-10√
x = 20
Solve:4 - 3x = 104 - 3x - 4 = 10 - 4-3x = 6-3x/-3 = 6/-3x = -2Check:4 - (3 x -2) = 104 - (-6) = 104 + 6 = 1010 = 10
The answer depends on where the missing number is meant to be. If 2, 4, 6, 10, 26, X: then X = 72 If 2, 4, 6, 10, X, 26: then X = 16.8 If 2, 4, 6, X, 10, 26: then X = 6.6 If 2, 4, X, 6, 10, 26: then X = 5.4 If 2, X, 4, 6, 10, 26: then X = 1.2 If X, 2, 4, 6, 10, 26: then X = 6
6 x 10 x 4=240
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
x-6-x-4=10-x-10=10-xx=20
60 %. 10-4 = 6. 6/10 = x/100 Cross multiply and solve for x.
x = 20
To solve for x: 2x2 + 10 = 58 2x2 = 48 x2 = 24 x = √24 x = √4 × √6 x = 2√6
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
3x+4=10 To solve: 3x+4=10 3x=6 x=2
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
4x=-10 x=-2.5
Set up the equation and solve for x: 2/3(x) - 6 = -10 (next add 6 to each side to separate knowns from unknowns) 2/3(x) = -4 (next multiply both sides by 3 to simplify) 2x = -12 (next divide both sides by 2 to solve for x) x = -6 to prove: substitute x with -6 (hint: 2/3 of -6 = -4) 2/3(-6) - 6 = -10 -4 - 6 = -10 -10 = -10
Solve:4 - 3x = 104 - 3x - 4 = 10 - 4-3x = 6-3x/-3 = 6/-3x = -2Check:4 - (3 x -2) = 104 - (-6) = 104 + 6 = 1010 = 10
