Answer:

x=7

y=11

z=7

Step-by-step explanation:

x + y + z = 25

y+z= 18

Z= 7

Substitute the third equation into the second

y+z=18

y+7 = 18

y = 18-7

y = 11

Now substitute y=11 and z=7 into the first

x +y+z = 25

x+11+7 = 25

x+18 = 25

x = 25-18

x=7

What value of x is in the solution set of 2x – 3 &gt; 11 – 5x?<br><br> –3 <br> 0<br> 2<br> 4
Makovka662 [10]

Answer:

x = 4

Step-by-step explanation:

Solve the inequality

2x - 3 > 11 - 5x ( add 5x to both sides )

7x - 3 > 11 ( add 3 to both sides )

7x > 14 ( divide both sides by 7 )

x > 2

The only value of x greater than 2 is 4, thus

x = 4 is in the solution set
