Question

1)x+(x+15)=117 x=?
2)x+(x×5)=282 x=?​

Answer 1

1)

$x + (x + 15) = 117$

$x + x + 15 = 117$

$1x + 1x + 15 = 117$

$2x + 15 = 117$

$2x = 117 - 15$

$2x = 102| \div 2$

$x = 51$

2)

$x + (x \times 5) = 282$

$x + (5x) = 282$

$x + 5x = 282$

$1x + 5x = 282$

$6x = 282| \div 6$

$x = 47$
