Question

A) 1+(5+3): 2 =
B) 3. (4-2). 2 + (3-1)- 4 =
C) 6+(3-X). 2-5-12: (-3)=​

Answer 1

$1 + ( 5 + 3 ) : 2 = \\ \\ 1+\frac{8}{2} \\ \\ 1+4 \\ \\ = 5 \\ ............................ \\ \\ 3(4-2) \times 2+(3-1)-4 \\ \\ 3\times 2\times 2+3-1-4 \\ \\ 6\times 2+3-1-4 \\ \\ 12+3-1-4 \\ \\ 14-4 \\ \\ = 10 \\ \\ .............................. \\ \\ 6 + ( 3 - x ) \cdot 2 - 5 - 12 : ( - 3 ) = \\ \\ 1+\left(3-x\right)\times 2-\frac{12}{-3} \\ \\ 1+\left(3-x\right)\times 2-\left(-4\right) \\ \\ 5+\left(3-x\right)\times 2 \\ \\ 5+6-2x \\ \\ 11-2x$
