Since both of the equations equal Y can substitute one for the Y and say that
X-1=3x+3
-4=2x
-2=x
Answer:
(a) see attachment
(b) E(x) = 226/105
Step-by-step explanation: see attachment
1/6(12z-18)=2z-3
12/6z-18/6 =2z-3
2z-3=2z-3
there are infinite solutions for this equation or all real numbers
Answer:
35-5a-3a-12-4=-8a+19
4a-12+7=4a-5
Unequal
Step-by-step explanation:
2:3:4 gives 9 equal parts.
1.20 divided by 9 is 0.133.
2 * 0.133 would be 0.266m
3 * 0.133 would be 0.399m
4 * 0.133 would be 0.533m
To check this calculate 0.533 + 0.399 + 0.266 would be 1.198m (close enough)
