Question

$30 = 6(8 + x)$
$\frac{2t + 3}{7} = 5$
solve the equation​

Answer 1

ANSWER:

6(8+x)=30

8+x=30÷6

8+x=5

x=5-8

x= -3

2t+3= 5×7

2t+3=35

2t=35-3

2t=32

t=32÷2

t=16

Answer 2

$1) \: 30 = 6(8 + x)$

$30 = 48 + 6x$

$30 - 48 = 6x$

$- 18 = 6x$

$x = \frac{6}{ - 18}$

$x = - \frac{1}{3}$

$2) \: \:$

$\frac{2t + 3}{7} = 5$

$2t + 3 = 7 \times 5$

$2t + 3 = 35$

$2t = 35 - 3$

$2t = 32$

$t = \frac{32}{2}$

$t = 16$
