Question

X+ x +x =21 y + y + x =19 t + x + y =15 then x + t × y =?

Answer 1

Since, it is given that $x + x + x =21$\

$3x = 21$

$x = \frac{21}{3}$

So, x = 7

It is given that $y + y + x = 19$

$2y + x = 19$

$2y + 7 = 19$

$2y = 19 - 7$

$2y = 12$

y = 6

Now, it is given that $t + x + y = 15$

$t + 7 + 6 = 15$

$t + 13 = 15$

t = 15 - 13

t = 2

So, we get x = 7, y = 6 and t = 2

We have to evaluate the value of the expression $x + t \times y$

According to BOD MAS, we will first use the multiplication operator and then addition operator.

$x + (t \times y)$

= $7 + (2 \times 6)$

= $7 + 12$

= 19

So, the value of the expression is 19.
