Find what x is? 5×3>4+8+x a good help for your brain! ​
MaRussiya [10]

Answer:

x = 2.25 or any number greater

Step-by-step explanation:

5x3 > 4 + 8 + x

Make them equal to each other to get x

5x3 = 4 + 8 + x

(5x)(3) = 12 + x

- x - 3   - 3  - x

4x = 9

\frac{4x}{4} = \frac{9}{4}

x = 2.25

Once you get x plug it in to get the truth of the expression
