Question

Solve the equation using addition or subtraction.

Answer 1

Answer:

1. Solve the equation using addition or subtraction.

$4=q+13$

Taking like terms on one side, we get

$4-13=q$

=> $-9=q$

or $q=-9$    (option C)

2. Solve the equation using addition or subtraction.  

$5.5= -2+d$

Taking like terms on one side, we get

$5.5+2=d$

So, $d=7.5$    (option B)

3. Solve the equation using multiplication or division

$-7y=28$

Dividing both sides by 7, we get

$-y=4$

or $y=-4$    (option A)

4. Solve the equation using multiplication or division

$-13=\frac{m}{-5}$

Cross multiplying -13 and -5 to get the value of m

$m=(-13)(-5)$

$m= 65$      (option C)

Answer 2

1. C -9
2. B 7.5
3. A -4
4. C 65
