Answer:
[tex]\bf x=10[/tex]
Step-by-step explanation:
[tex]\tt 4x+3(x-1)=67[/tex]
Use the distributive property to multiply 3 by x-1:-
[tex]\tt 4x+3x-3=67[/tex]
Combine 4x and 3x = 7x:-
[tex]\tt 7x-3=67[/tex]
Add 3 to both sides:-
[tex]\tt 7x=70[/tex]
Divide both sides by 7:-
[tex]\tt \cfrac{7x}{7} =\cfrac{70}{7}[/tex]
[tex]\tt x=10[/tex]
