7+9=16
Step-by-step explanation:
let us add the numbers step by step:
Just add the numbers like this [1+3,2+4,3+5,4+6,5+7,6+8,7+9…]
you get the answer 7+9=16
T) -7x+10y=20. M) -3x+y=-2 - ,
2(8x-5y)=35(2) -1(x+y)=-6(-)
-7x+10y=20. -3x+y=-2
16x-10y=70. -x-y=6
9x=90. -4x=4
[x=10] [x= -1]
-7(10)+10y=20. -3(-1)+y=-2
-70+10y=20. 3+y=-2
10y=90. [y= -5]
[y=9]
