Answer:
x = -1
Explanation:
4(x + 2) - 3x = 7
[tex]\sf {use \ distributive \ method: \ a(b + c) = ab + ac[/tex]
4x + 8 - 3x = 7
[tex]\sf exchange \ sides[/tex]
4x - 3x = 7 - 8
[tex]\sf simplify[/tex]
x = -1
Check for answer:
4( x + 2 ) - 3x = 7
[tex]\sf insert \ x = -1[/tex]
4(-1 + 2) - 3(-1) = 7
4(1) + 3 = 7
7 = 7 Hence verified
