First Answer:
x = 12
First Step-by-step explanation:
12 + x = -3(4 - x)
12 + x = -12 + 3x
- x - x
—————————
12 = -12 + 2x
+ 12 + 12
—————————
24 = 2x
24/2 = 2x/2
12 = x
Second Answer:
No solution
Second Step-by-step explanation:
2(x - 1/2) = 8 + 2x
2x - 1 = 8 + 2x
+1 +1
—————————
2x = 9 + 2x
- 2x - 2x
—————————
0 = 9

Hello There!
All we must do is plug in the numbers and solve:
8(0.25)-1=14=2-1+14=1+14=15
Hope it helps
So they’re supplementary angles which means that they add up to 180°… The equation would be: 5w+1+7w-7=180
5w+1+7w-7=180 (combine like terms)
12w-6=180
+6 +6
12w=186
w=15.5
Im not sure what they’re asking for but if they’re asking for w, your answer is 15.5, if they’re asking for the angle measure on the left, your answer is 78.5° & if they’re asking for the angle measure on the right, your answer is 101.5° :) hope this helps
