11.) 3
12.) 3x+6 = 33 Transpose the equation
3x+6 = 33 Transpose the equation3x=33-6
3x+6 = 33 Transpose the equation3x=33-63x=27
3x+6 = 33 Transpose the equation3x=33-63x=273x/3=27/3
3x+6 = 33 Transpose the equation3x=33-63x=273x/3=27/3X=7
13.) We are given that x-y=5 and 4x+y=5, therefor x=y+5 and 4*[y+5]+y=5.
We are given that x-y=5 and 4x+y=5, therefor x=y+5 and 4*[y+5]+y=5.So 5y=5–20=-15 or y=-3.
We are given that x-y=5 and 4x+y=5, therefor x=y+5 and 4*[y+5]+y=5.So 5y=5–20=-15 or y=-3.Hence x=2, The two numbers (x,y)=(2,-3).
We are given that x-y=5 and 4x+y=5, therefor x=y+5 and 4*[y+5]+y=5.So 5y=5–20=-15 or y=-3.Hence x=2, The two numbers (x,y)=(2,-3).Proof: x-y=2-(-3)=2+3=5 and 4x+y=8–3=5.
14.) 6x+3=39
6x+3=396x=39-3
6x+3=396x=39-36x=36
6x+3=396x=39-36x=366x/6=36/6
6x+3=396x=39-36x=366x/6=36/6X=6
15.) 4/x+5=9
4/x+5=94/x=9-4
4/x+5=94/x=9-44/x=5
4/x+5=94/x=9-44/x=5X=20
16.) You can call an unknown number 'x'. The difference of a number and 8 can then be written as 'x-8'. Twice that amount would be 2(x-8). If it's equal to 2, you can say 2(x-8)=2. That is your equation.
