Find the solution to the system of equations.
You can use the interactive graph below to find the solution. −2x+2y=−4
3x+3y=−18
x=
y=

x = -2, y = -4

Step-by-step explanation:

-2x+2y = -4 (1)

3x+3y = -18 (2)

(1) 2y = 2x - 4

y = x - 2

(2) 3x + 3(x - 2) = -18

3x + 3x - 6 = -18

6x = - 12

x = -2

y = (-2) - 2 = -4

x = -2, y = -4

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
