simplify the expression 16+7y-8 rewrite as 7(y-8)7•y= 7y 7•8= 56 7y-56 = -49y answer= 16+ (-49y)
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
It cannot be simplified any further, so it is: 2x + 7y
a + 7y
It is: 8+7y
That depends what you want it to equal at the end.
simplify the expression 16+7y-8 rewrite as 7(y-8)7•y= 7y 7•8= 56 7y-56 = -49y answer= 16+ (-49y)
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
7y-8 = 6y+1 7y-6y = 1+8 y = 9
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7

5y+8=7y 2y=8 y=4
It cannot be simplified any further, so it is: 2x + 7y
2y+3y-7y+4=16 -2y=12y=-6Check it-12-18+42+4=16-30+46=1616=16
12y - 4 = 7y + 165y = 20y = 4
y = 14
