Answer:
Your answer would be 4! Or if you want it in fraction form then it would be 7/3!
7x-1/2(8x+2)=6
We simplify the equation to the form, which is simple to understand
7x-1/2(8x+2)=6
Simplifying:
7x-0.5*(8x+2)=6
Reorder the terms in parentheses
7x+(-4x-2)=6
Remove unnecessary parentheses
+7x-4x-2=+6
We move all terms containing x to the left and all other terms to the right.
+7x-4x=+6+2
We simplify left and right side of the equation.
+3x=+8
We divide both sides of the equation by 3 to get x.
x=7/3
Answer: 76.2%
Step-by-step explanation:762/1000
{ x + 2y = 4 * ( 3 )
-3 x + 2y = -4
3 x + 6 y = 12
-3 x + 2 y = -4
---------------------
8 y = 8
y = 8 / 8
y = 1
For x :
x + 2 y = 4
x + 2*(1 ) = 4
x + 2 = 4
x = 4 - 2
x = 2
Answer C ( 2 , 1 )
