Answer:
all down below. sorry for the wait
Step-by-step explanation:
[tex]4x+10=26\\4x+10-10=26-10\\4x=16\\4x/4=16/4\\x=4\\\\\frac{1}{2}x+3=28\\ \frac{1}{2}x+3-3=28-3\\\frac{1}{2}x=25\\\frac{1}{2}x/\frac{1}{2}=25/\frac{1}{2}\\x=50\\\\x+3x=x+6\\5x=6\\5x/5=6/5\\x=1.2\\\\20x+10x-5=25\\30x-5=25\\30x-5+5=25+5\\30x=30\\30x/30=30/30\\x=1\\\\x^2+5=30\\x^2+5-5=30-5\\x^2=25\\\sqrt{x^2}=\sqrt{25}\\x=5\\\\3x-3=30\\3x-3+3=30+3\\3x=33\\x=11[/tex]
