Find the solution set for the equation. use properties to justify your solution
2x-3=9-x

x=4

Step-by-step explanation:

2x-3=9-x

1. add 3 to -3 and 9, which will cancel out -3 and leave you with 2x=12-x

2. add x to 2x and -x which will cancel out -x and leave you with 3x (there will always be a 1 in front of x if it has no variable in front of it x=1) which will leave you with 3x=12

3. divide 12 by 3 and you get 4..so x=4

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
