Question

plz plz solve it step by step​

Answer 1

Answer:

i) m=5/2

ii) a=1

iv) n=1

v) b=7

Step-by-step explanation:

$6m+5=20\\6m=20-5\\m=15/6=5/2\\\\\therefore m=5/2$

$\frac{a}{2} +\frac{1}{2} =1\\\frac{a}{2}=1-1/2\\a=1/2*2=1\\\\\therefore a=1$

$3n+11=14\\3n=14-11\\n=3/3=1\\\\\therefore n=1$

$10b-7=63\\10b=63+7\\b=70/10=7\\\\\therefore b=7$
