Try multiplying each side of the equation by 3, and then
watch out when the answer jumps off the paper at you.
Answer:
z=16
Step-by-step explanation:
We know for sure that since A and B are parallel that 1, 4, 5, and 8 are equal.
So then the equation is simply 123=7z+11---> 7z=112----> z=16
Answer:
w = -4
Step-by-step explanation:
<u>Step 1: Distribute</u>
-2w - 14 = 2(w + 1)
-2w - 14 = 2w + 2
<u>Step 2: Add 2w to both sides</u>
-2w - 14 + 2w = 2w + 2 + 2w
-14 = 4w + 2
<u>Step 3: Subtract 2 from both sides</u>
-14 - 2 = 4w + 2 - 2
-16 = 4w
<u>Step 4: Divide both sides by 4</u>
-16 / 4 = 4w / 4
<em>-4 = w</em>

Answer: w = -4
Step-by-step explanation:
b^2=4ac
b= -26, a=1, c=?
-26^2=4*1*c
676=4c
c=676/4
c=169
3x - 2y = 10
10x + 2y = 8 (everything *2)
minus
Therefore final equation is -7x = 2 B
