Brainliest! If 2a+4b=5 and a is equal to three times b, what is 3a?

RoseWind [281]

Answer:

3a = $\frac{9}{2}$

Step-by-step explanation:

Given

2a + 4b = 5 ← substitute a = 3b into the equation

2(3b) + 4b = 5

6b + 4b = 5

10b = 5 ( divide both sides by 10 )

b = $\frac{5}{10}$ = $\frac{1}{2}$

Now

a = 3b = 3 × $\frac{1}{2}$ = $\frac{3}{2}$ , thus

3a = 3 × $\frac{3}{2}$ = $\frac{9}{2}$
