Question

1) 3 + 8 = − 1 6 2) 7x+ 3 = 17

Answer 1

1) 3х+8= -16

3х=-16-8

3х=-24

х= -24:3

х -8

2) 7х+3=17

7х=17-3

7Х=14

х=14:7

х=2

Answer 2

It looks like you've provided two mathematical equations. Let's solve them one by one:

1. $3 + 8 = -162$

This equation is not valid. The left-hand side (3 + 8) equals 11, and the right-hand side (-162) is a completely different number. There seems to be a mistake in the equation.

2. $7x + 3 = 17$

To solve for $x$, we'll isolate it on one side of the equation:

Subtract 3 from both sides:

$7x = 14$

Now, divide both sides by 7:

$x = 2$

So, the solution to the second equation is $x = 2$.
