Answer:

a) one solution(x = 9)

b) no solution

c) infinite solutions

Step-by-step explanation:

a) To solve this equation, we can add 4 on both sides in order to isolate x:

x - 4 =5

+ 4 + 4

x = 9

Since x equals 9, that counts as only one solution, as there is only one value of x that makes the equation true.

b) We start by subtracting 2x from both sides to combine the variable terms:

2x - 6 = 2x + 5

-2x -2x

-6 = 5

The statement, -6 = 5 is never true and it is not dependent on the value of x. This means there are no solutions to this equation.

c) We can start by subtracting 3x from both sides to combine the terms with x:

3x + 12 = 3x + 12

-3x -3x

12 = 12

The statement above is always true, and no matter the value of x, it will always be true. This means there are infinite solutions to the equation.

Step-by-step explanation:

Remember the Order of Operations:

Parentheses

Exponents

Multiplication

Division

Addition

Subtract

*But always solve from left to right so there can be times where you either have to do division before multiplication or subtraction before addition

1. 14 + 18 ÷ 2 x 18 – 7

14+9 x 18-7

14+162-7

176-7

169

2. 15 x 10 + 12 ÷ 3 + 9

150+12÷3+9

150+4+9

154+9

163

3. 8 x 4 + 9 – 9 + 18

36+9-9+18

45-9+18

36+18

4. 2 - 1 + 5 x 4 x 11

2-1+20x11

2-1+220

1+220

221

5. 60 – 9 x 8 ÷ 8 x 6

60-72÷ 8 x 6

60-9x6

60-54

6. (10 ÷ 5)3 + 100 – 9 x 11

(2)3+100-9x11

6+100-9x11

6+100-99

106-99

7. 3 x 8 x 2 – 42 + 5

24x2-42+5

48-42+5
