Sagot :
1.5x+3=18
5x+3-3=18-3(subtract 3 from both sides)
5x=15
5x=15 (divide both sides by 5)
5 5
X=3
2.4(x-4)=0
X=4
3.10x+11=12-3
10x+11=(12+(-3)) (simplify both sides)
10x+11=9 (combine like terms)
10x+11-11=9-11 (subract 11 from both sides)
10x=-2
10 10 (divide both sides by 10)
X= -1
5
4.3x+6=-2x+6
X=0
