Answer:
x = 3
Step-by-step explanation:
Step 1: combine like terms
On the left side, you can combine 4x and 3x to get 7x and the right side is already simplified
Now we have 7x+10=40-3x
Step 2: subtract 10 from both sides
10-10 = 0 and 40-10 = 30
Now we have 7x = 30-3x
Step 3: Add 3x to both sides
7x +3x = 10x and 30-3x+3x = 30
Now we have 10x =30
Step 4: divide by 10 on both sides
10x/10 = x and 30/10= 3
Therefore, we have x =3
