X = 5
add the 10 on the left side to the right side and you get 4x = 20. 20 divided by 4 is 5.
196 + x = 500
Subtract 196 from both sides:
196 on the left is cancelled out, and you’re left with x = 304

Answer:
10^-5
Step-by-step explanation:
Answer:
1/2.(x+12)=4x-1
x+12=2(4x-1)
x+12=8x-2
Group like terms
12+2=8x-x
14=7x
Divide both sides by 7
x=2
Step-by-step explanation:
Step-by-step explanation:
(-6x +3y=9 )×4
( 10x+4y)×3
-24x +12y =36
30x+12y= -18
-24x+12y- (30x+12y)= 36-(-18)
-54x = 54
x= -1
by using 10x +4y = -6
apply x= -1
-10+4y= -6
4y= -6 +10
4y=4
y=1
so the answer is x=-1 and y= 1
