Hello!
0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1
Your answer is x = -1. I hope this helps!
Answer:
11
Step-by-step explanation:
4x - y = 13 >>>> y = 4x - 13
2x + y = 17 >>>> y = -2x + 17
so
4x - 13 = -2x + 17
4x + 2x = 17 + 13
6x = 30
x = 5
y = 4x - 13 = 4(5) - 13 = 7
then
3y - 2x = 3(7) - 2(5) = 21 - 10 = 11
