Answer:
x = 3
Step-by-step explanation:
Use the distributive property to multiply 4 by 5x+3. Subtract 14x from both sides. Combine 20x and −14x to get 6x. Subtract 12 from both sides. Subtract 12 from 30 to get 18. Divide both sides by 6. Divide 18 by 6 to get 3.
Answer:
20x+12=14x+30
6x=18
x=3
Step-by-step explanation:
First, apply the distributive property:
4(5x+3) = 4 · 5x + 4 · 3 = 20x+12
Now, we have this equation
20x+12=14x+30
We need to group the elements now.
So, to bring all the elements with an "x," we subtract 14x from both sides.
20x-14x+12=14x+30-14x
We have this now
6x+12=30
Now, let's subtract 12 on both sides
6x+12-12=30-12
6x=18
Divide both sides by 6
x=3
