PLEASE MARK ME BRAINLIEST
The goal of this equation is to solve for x. So, we can start by combining like terms.
(16x) and (5x) are like terms, so we would subtract (5x) over to the other side.
131 + 16x -5x = -331 + 5x - 5x
131 + 11x = -331
Then, we can combine the other like terms, which would be (131) and (-331). Subtract 131 on both sides.
131 - 131 + 11x = -331 - 131
11x = -462
Now, we need to divide the number before x, or the coefficient.
11x/11 = -462/11
x = -42
Hello,
Let's assume f the age of the father,
s the age of the son.
<span>The age of a father is 2 less than 7 times the age of his son ==> f=7s-2 (1)
</span>
<span>In 3 years, the sum of their ages will be 52 ==>(f+3)+(s+3)=52 (2)
(2)==>f+s+6=52
==>f+s=46 (3)
(3) and (1) ==>7s-2+s=46
==>8s=48
==>s=6
f=46-6=40
</span>
