Question

4(5x+3)=14x+30 not sure if i understand

Answer 1

20x+12=14x+30

6x=18

x=3

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

Answer 2

x = 3

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.
