Solve Linear Equation: px + q = r
Choose all that are correct.

a.) 5x + 10 = 12
x= 5/2

b.) 3x + 10 = 8
x= 2/3

c.) 9x + 15 = 36
x= 7/3

d.) 8x + 12 = 24
x= 3/2

Answer 1

C & D are both, and only correct.

a.)

5x + 10 = 12

x = 2/5 NOT 5/2, so this is in fact INCORRECT.

b.)

3x + 10 = 8

x = - 2/3 NOT 2/3, This too is INCORRECT.

c.)

9x + 15 = 36

x = 7/3. This is CORRECT!

d.)

8x + 12 = 24

x = 3/2. This is CORRECT!
