3x-6+10x+15=35
10x+3x=35-15+6
13x=26
x=2
Answer: 2
Step-by-step explanation: (2x-4)
Answer:
A; infinitely many solutions
Step-by-step explanation:
first, let's simplify the first equation to make it simpler.
divide both sides by 5
y=3x-8
new system
y=3x-8
y=3x-8
as you can see, they are the same.
not mandatory but useful!⬇⬇⬇⬇
just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.
3x-8=3x-8
add 8 to both sides; subtract 3x from one side
0=0
the answer is A, Infinitely many solutions.

2x+38=50
2x+38-38=50 -38
2x =12
2x/2 =12/2
x=6
