Answer:
9
Step-by-step explanation:
1. To find how 3x+10=16, we must subtract 10 from both sides.
-10 -10
2. now we have 3x=6, we divide 3 from both sides
3 3
3. we end with x=2.
Now we know x=2, we plug in 2 into our second equation.
1. 4(2)+1 we multiply 4 times 2.
2. we are then left with 8+1, which equals 9.
