r + 35 = 74

Step-by-step explanation:

1) Given the equation:

You can rewrite it in the following form:

You must solve for "z". To do it, you can multiply both sides of the equation by 12.

Then you get this solution:

2) The equation given is:

Now, in order to solve for the variable "g", you can divide both sides of the equation by 5.

Then you get the following result:

3) Given the equation:

You can solve for "d" adding 21 to both sides of the equation.

So the value of "d" is:

4) Having this equation:

You must subtract 35 from both sides of the equation in order to find the value of the variable "r".

This is:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
