Answer:
x=1, y=-5
Step-by-step explanation:
Given equations are:

In order to solve the equation
Multiplying Eqn 1 by 5 and eqn 2 by 3 and subtracting them
So,
Eqn 1 becomes
15x+50y=-235
Eqn 2 becomes
15x-21y=120
Subtracting 2 from a
15x+50y - (15x-21y) = -235-120
15x+50y-15x + 21y = -355
71y = -355
y = -355/71
y =-5
Putting y= -5 in eqn 1
3x+10(-5) = -47
3x -50 = -47
3x = -47+50
3x = 3
x = 3/3
x = 1
Hence the solution is:
x=1, y=-5
11x10=110
110+40=150
150/6=25
25-8=17
17 is the number.

Answer:
(9 x 0) + 4=4
Step-by-step explanation:
2.5*7 = 17.5. If it's easier for you, multiply 2.5 by 5 then add 2.5*2.
