Answer:
Step-by-step explanation:
10:2 = 5:1
6:3 = 2:1
12x+1+5x-3=117
(combine like terms)
17x-2=117
(subtract 2 from each side)
17x=115
(divide each side by 17)
x=6.7

Step-by-step explanation:
Answer:
0=0
Step-by-step explanation:
Simplifying
-5(x + -7) = 35 + -5x
Reorder the terms:
-5(-7 + x) = 35 + -5x
(-7 * -5 + x * -5) = 35 + -5x
(35 + -5x) = 35 + -5x
Add '-35' to each side of the equation.
35 + -35 + -5x = 35 + -35 + -5x
Combine like terms: 35 + -35 = 0
0 + -5x = 35 + -35 + -5x
-5x = 35 + -35 + -5x
Combine like terms: 35 + -35 = 0
-5x = 0 + -5x
-5x = -5x
Add '5x' to each side of the equation.
-5x + 5x = -5x + 5x
Combine like terms: -5x + 5x = 0
0 = -5x + 5x
Combine like terms: -5x + 5x = 0
0 = 0
Solving
0 = 0
