x/5 = 8/21 x = 8/21 * 5 x = 1.904761905
3x-2 = 2x+3 3x-2x = 3+2 x = 5
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
5.
x=5
-2 plus 5 equals +3
cross multiply 3/6=y/10 30=6y y=5
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
2 over 3 = 18 over x+5... x=22 because (x+5) needs to equal 27 for the equation to be true.
3
3
x= -.5
a/5 + 3 = 8 a/5 = 5 a = 25
If sin (theta) is 3/5, then sin2 (theta) is (3/5)2, or 9/25.
3/5 divided by 3/8 equals 24/15 which can be simplified to 8/5 or 1 3/5.
x/3 + 5 = 11 Subtract 5 from both sides: x/3 = 6 Multiply both sides by 3: x = 18
The answer is n = 5.
