Answer 1

1) 15х+49=149
15х=149-49
15х=100
х=100:15
х=6 10/15=6 2/3
2) 13+10у=163
10у=163-13
10у=150
y=150:10
y=15
3) 9y-54=162
9y=162+54
9y=216
y=216:9
y=24
4) 181-8x=45
181-45=8x
136=8x
x=136:8
x=17

Answer 2

Answer 3

To solve this system of linear equations, let's go through each equation one by one.

1. $15x + 49 = 14913$

   Subtract 49 from both sides: $15x = 14864$

   Divide both sides by 15: $x = 990.$

2. $10y + 1639 = 1639$

   Subtract 1639 from both sides: $10y = 0$

   Divide both sides by 10: $y = 0.$

3. $181 - 8x = 45$

   Subtract 181 from both sides: $-8x = -136$

   Divide both sides by -8: $x = 17.$

So, the solution to the system of equations is $x = 990$ and $y = 0$.
