Question

Solve the following equations (1) 5+ 4(t - 7)=13
(2) 2b/3 - 5 = 3​

Answer 1

Answer:

please mark in brainleast

Step-by-step explanation:

1.ans 5+4t-28=13

5-28+4t=13

-23+4t=13

4t=13+23

4t=36.

t=36/4

t=9

2.ans 2b/2=3

2b=3×2

2b=6

b=6/2

b=3

Answer 2

$\underbrace \text{Answer:}$

$\bf{1)} \: \text{5 + 4(t - 7) = 13}$

$\: \: \implies \: \text{5 + 4t - 28 = 13}$

$\: \: \: \: \: \implies \text{4t - 23 = 13}$

$\: \: \: \: \: \: \: \: \implies \text{4t = 13 + 23}$

$\: \: \: \: \: \: \: \: \: \: \implies \sf{t = \cancel\frac{36}{4} }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \implies \bf \red{t = 9}$

$\bf{2)} \sf{ \frac{2b}{3} - 5 = 3}$

$\: \: \implies \sf{ \frac{2b}{3} = 3 + 5 }$

$\: \: \: \: \implies \sf{2b = 8 \times 3}$

$\: \: \: \: \: \: \implies \sf{b = \cancel\frac{24}{2} }$

$\: \: \: \: \: \: \: \: \implies \frak \red{b = 12}$
