Let's first solve the first equation:
9(143-13x)=23Distribute the 9 on the left side1287 - 117x = 23Subtract 1287 from both sides-117x = -105Divide by -117 on both sidesx = 9
Now let's solve the second equation:
17(5x-16)=23Distribute the 17 on the left side85x - 272 = 23Add 272 to both sides85x = 51Divide by 85 on both sidesx = 6
Therefore, the solution set is x = 9 and x = 6.
Let's first solve the first equation:
9(143-13x)=23
Distribute the 9 on the left side
1287 - 117x = 23
Subtract 1287 from both sides
-117x = -105
Divide by -117 on both sides
x = 9
Now let's solve the second equation:
17(5x-16)=23
Distribute the 17 on the left side
85x - 272 = 23
Add 272 to both sides
85x = 51
Divide by 85 on both sides
x = 6
Therefore, the solution set is x = 9 and x = 6.
