Start by working inside the parenthesis first, as always. 7 + 3 = 10. So now we have 4(10)=4×x+4×7. We will distribute the left side and multiply to get 40. Now we have 40 = 4 × x + 4 × 7. Now the order of operations tells us that we have to do multiplication and division first. We only have multiplication, between the 4 and the x, and the 4 and the 7. Multiplying we will end up with 40 = 4x + 28. Now subtract 28 from both sides to get 12 = 4x. Divide by 4 to get that x = 3. Choice A from above.
