Me : 4 x + 8 y = 64
My friend: 8 x + 16 y = 128
A ) 4 * 4 + 8 y = 64
16 + 8 y = 64
8 y = 64 - 16
8 y = 48
y = 48 : 8
y = 6 ( me and my friend work 6 hours at the second job )
B ) The number of hours we each work at the first job are also the same.
Well, we know that y=1/2x+5 from the first equation. if we substitute that into the second equation, it becomes 2x + 1/2x +5 =1. solve for x. 2x+1/2x= -4, 2 1/2x=-4, x=-1.6. plug that in to one of the equations. 2(-1.6)+y=1, -3.2+y=1, y=-2.2. the solution is (-1.6, -2.2)
I think the answer is 12 because the greatest common factor of 24 and 36 is 12.
Hope this helped☺☺

A verbal statement is an expression that uses words instead of numbers. A math verbal model is when a mathematical model is completely written out in words instead of numerals. Most real world problems are stated using words and need to be translated into mathematical statements.
