Answer: 2=x
Explanation:3x+4=7x-4
-3x -3x
4=4x-4
+4 +4
8=4x
(divide each side by 4)
2=x
Step-by-step explanation:
3x+4=7x-4
add 7x to each side of equation 4x+3x+-7x=-4x+7x+-7x
combine like terms 7x+-7x=0
4+ -4x =-4 +0
4+-4x= -4
add -4 to each side of equation 4+ -4 +-4x=-4+-4
combine like terms -4 +4=0
0+ -4x = -4+ -4
combine like terms -4+-4=-8
-4x =-8
divide each side by-4
x=2
simplifying
x = 2
