Answer:

Putting the value in x = 2 , y =4 in 2x - 2y we get,

2 × 2 - 4× 2= 4-8 = -4

Putting the value in z = 3 in z - 5 we get,

z - 5 = 3 - 5 = -2

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller numbe

snow_tiger [21]

3y = 5x+30 , y+5x = 50

using elimination method ...

3y-5x=30
+ y+5x=50
——————
4y = 80
y= 20

so using one of the original equations..

20 + 5x = 50
5x = 30
x =6

x = 6
y = 20
