Product of 8 and a sum is 8 times the sum
sum is plus so sum of 4 and a number is 4+n
8(4+n)=112
last equation matches
Factor 4 out of 4x+20.
4(x+5)
The answer to your question is 6,643,783
The solutions are (2.1925, 5.1925) and (-3.1925, -0.1925)
<em><u>Solution:</u></em>
Given that,

<em><u>We have to substitute eqn 1 in eqn 2</u></em>






Substitute x = 2.1925 in eqn 1
y = 2.1925 + 3
y = 5.1925
Substitute x = -3.1925 in eqn 1
y = -3.1925 + 3
y = -0.1925
Thus the solutions are (2.1925, 5.1925) and (-3.1925, -0.1925)
