Can someone please help me with this(Will mark branliest) :)

Answer:
X=3 (hope this helps)
Step-by-step explanation:
So what you want to see if they are equal (in this case they are) so we have 10 plus 12x and we also have 15x plus 1
10 + 12x = 15x + 1 (solve for x)
-15x + 12x=1 - 10
-3x = -9
x=3
lets see if our answer is correct :)
15 x 3= 45 + 1 = 46
12 x 3 = 36 + 10= 46
