Question

For which equation would x = 8 not be a solution?

a. 8 x = 64
b. 4 x = 48
c. 10 x = 80
d. 9 x = 72

Answer 1

4x = 48

Explanation:

Since x = 8,

4x = 48

4 * 8 = 32

So 32 is the LHS and 48 is the RHS.

Since the LHS is not equal to the RHS, x=8 is not a solution to the equation 4x = 48

Hope this answer is helpful!!

Answer 2

b. 4x = 48

Explanation:

If you look closely an multiply 4 x 8, it equals 32, not 48

The other equations:

8 x 8 does equal 64

10 x 8 does equal 80

9 x 8 does equal 72

It's pretty simple once you try each problem first

Hope this helps!
