Answer:
Step-by-step explanation
subtract 8 from both sides
8-2x-8=-4x+4-8
simplify
-2x=-4x-4
add 4x to both sides
-2x+4x=-4x-4+4x
Simplify
2x=-4
divide both sides by 2
2x/2=4/2
simplify
x=-2
X-5) = 2(x-1)
3x-15 = 2x - 2
x - 15 = -2
x = 13
These are all linear equations:<span>y = 2x + 1
5x = 6 + 3y
<span>y/2 = 3 − x</span></span>
Answer:
3/5
Step-by-step explanation:
1/2=2/4
2+1=3
1+4=5
3/5
Answer: D = 70
A = 30
Explanation: d is parallel to 70 degrees, 40 is parallel to e, and the whole set of angles is 180 so 180 - 2(70) + 2(40) = 30 so D = 70 and A = 30
