Question

For each value of x, determine whether it is a solution to 3x + 5 = 8.

Answer 1

Answer:

-6:No

-2:No

7:No

8:No

The only number to make this equation true is 1

Step-by-step explanation:

I will substitute each value in place of the variable. Hopefully you understand PEMDAS

3(-6)+5=8

-18+5=8

-13=8

-13 does not equal 8 so false.

3(-2)+5=8

-6+5=8

-1=8

-1 doe not equal 8 so false

3(7)+5=8

21+5=8

26=8

26 does not equal 8 so false

3(8)+5=8

24+5=8

29=8

29 does not equal 8 so false

Let's see what would make this true:

3x+5=8

3x=3

×=1
