Please kung sino makasagot nito i follow ko, brainliest, at react heart sa ibang answers niya rin.

Maawa naman kau wag mag nonsense :(


Sagot :

1.How to solve your problem

+ 13=11

Subtract 13 from both sides of the equation

+ 13= 11

+ 13-13=11-13

Simplify

Subtract the numbers

Subtract the numbers

= --2

Solution

= -2

2.How to solve your problem

4y - 9 = - 2y

Add 9 to both sides of the equation.

4y -9=2y

4y-9+9= - 2y +9

Simplify

Add the numbers

4y= -2y+9

Add 2y to both sides of the equation

4y=2y+9

4y+2y= - 2y + 2y

Solution

3

y= -

3.How to solve your problem

5 - z = 2z - 37

Rearrange terms

5−=2−37

−+5=2−37

Subtract 5 from both sides of the equation

−z+5=2−37

−+5−5=2−37−5

Subtract the numbers

Subtract the numbers

−=2−42

Solution

=14

4.How to solve your problem

10−3(+2)=4−1

Distribute

10−3(+2)=4−1

10−3−6=4−1

Solution

5

a= -

7

7.How to solve your problem

6+3(1+)=(−7)−2

Rearrange terms

6+3(1+)=(−7)−2

6+3(+1)=(−7)−2

Solution

d=−1
