What do you think the answer is? Tell me and I will help you some more! :)
Hey there! :)
<em>First, let's substitute y with 0.8, and multiply by 8</em>
0.8 × 8 = 6.4
Here is the new equation:
4x + 6.4 = 40
<em>Now, subtract 6.4 from 40</em>
40 - 6.4 = 33.6
That means 4x = 33.6
<em>Divide both by 4</em>
4x ÷ 4 = x
33.6 ÷ 4 = 8.4
x = 8.4
Hope this helps :)
Answer:
Step-by-step explanation:
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
