Answer:
? = 5
Step-by-step explanation:
Replacing "?" with x and doing parenthesis first, we have:
[tex](4 * 3) + (4 * 7) = 4 * (? + ?)\\=(4 * 3) + (4 * 7) = 4 * (x + x)\\=12+28=4*2x[/tex]
Now simply doing algebra and solving for "x", we will get the value of "?":
[tex]12+28=4*2x\\40=8x\\x=\frac{40}{8}=5[/tex]
