Answer:
x=10
Step-by-step explanation:
3(4x-12) = 84
Divide each side by 3
3/3(4x-12) = 84/3
4x-12 =28
Add 12 to each side
4x-12+12 = 28+12
4x= 40
Divide each side by 4
4x/4 = 40/4
x = 10
<u><em>Answer:</em></u>
168
<u><em>Explanation:</em></u>
<u>Before we begin, remember the following:</u>
+ve * +ve = +ve -ve * -ve = +ve
+ve * -ve = -ve -ve * +ve = +ve
<u>Now, for the given problem we have:</u>
(-4) * (6) * (-7)
<u>Let's take the first two terms:</u>
(-4) * (6)
Based on the above rules, the product will be negative
<u>Therefore, </u>
(-4) * (6) = -24
<u>Now, the expression became:</u>
(-24) * (-7)
Again, based on the above rule, the product here will be positive
<u>Therefore,</u>
(-24) * (-7) = 168
Hope this helps :)
Answer:
x=88
Step-by-step explanation:
That third line is a transversal, making 92 and x supplementary to each other.
92+x=180
x=88
First multiply 2x - 5 by 3 amd will open the brackets
3(2x-5)-4=33
6x - 15 - 4 = 33
6x - 19 = 33
Take -19 to other side and its sign will be become +
6x = 33 + 19
6x = 52
x = 8.6
Well first lets do the distributive property so the left side is already done 28, now the right side -4 (2x+7) when you do that you get -8x-28. So now we have 28=-8x-28. So now I would move the -28 to the left side and when you move stuff to the other side you change the sign so the sign will be positive 28+28 which is 56. Now you have 56=-8x. Now divide both side by -8 to have -7=x
Your Answer: x = -7
