Answer:
2
Step-by-step explanation:
5x+2x+4=18
We move all terms to the left:
5x+2x+4-(18)=0
We add all the numbers together, and all the variables
7x-14=0
We move all terms containing x to the left, all other terms to the right
7x=14
x=14/7
x=2
Answer:
x=2
Step-by-step explanation:
put like terms together at one side:
5x+2x=18-4
7x = 14
divide by 7 on both sides:
x =2
