when we add -12 and 6 we get -6
after that we subtract -6 from -4 to get -10
Let x be the number of children
Let y be the number of adults
x + y = 4
4x + 7y = 19
Answer:
g=-6, x=-1
Step-by-step explanation:
23=−4g−1
Step 1: Flip the equation.
−4g−1=23
Step 2: Add 1 to both sides
−4g−1+1=23+1
−4g=24
Step 3: Divide both sides by -4
−4/-4g
=24/-4
g=-6

13=−4x+9
Step 1: Flip the equation
−4x+9=13
Step 2: Subtract 9 from both sides
−4x+9−9=13−9
−4x=4
Step 3: Divide both sides by -4
−4x/-4=
4/-4
x=−1
Answer:
27 =x
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
4x+7 = 5(x-4)
Distribute
4x+7 = 5x-20
Subtract 4x from each side
4x+7-4x = 5x-4x-20
7 = x-20
Add 20 to each side
7+20 = x-20+20
27 =x
move -7 to the right side of the equal sign which becomes +7
x=2+7
7 + 2 is 9
=9
