Answer:
y = 40 is the answer
Step-by-step explanation:
Let the number be y
10 more than 2 times a number = 10 + 2×y
equal to 2 times the number plus 50. = 2 × y + 50
10 + 2y = 2y + 50
combine the like terms
2y - 2y =50 - 10
0 = 40
the number supposes be 40 but the number is represented by 0
i think some thing is missing in your question
y supposes be 40 not 0 = 40
Hope this helps!
