Answer:
x=5
Step-by-step explanation:
Simplify the second equation by distributing the 3
8x-1=6x+9
Then subtract 6x on both sides, 8x-6x=2x
2x-1=9
Solve with PEMDAS, add 1 to both sides
2x=10
Divide both sides by 2, this should leave you with x=5
x=5
Plugging 5 into the original equation will give you 39
