Question

170-(25+x)=70 170-(25+z)=150

Answer 1

170-25-х=70 170-25-z=150
-x=215            -z=295
x=-215             z=295

Answer 2

To solve the equations, let's find the values of 'x' and 'z'.

1. 170 - (25 + x) = 70

First, simplify the expression inside the parentheses:

170 - 25 - x = 70

Now, combine like terms:

145 - x = 70

To isolate 'x', subtract 145 from both sides:

-x = 70 - 145 -x = -75

Now, multiply both sides by -1 to solve for 'x':

x = 75

So, the value of 'x' is 75.

2. 170 - (25 + z) = 150

Follow the same steps as above:

170 - 25 - z = 150

145 - z = 150

To isolate 'z', subtract 145 from both sides:

-z = 150 - 145 -z = 5

Now, multiply both sides by -1 to solve for 'z':

z = -5

So, the value of 'z' is -5.

Therefore, the solutions to the given equations are: x = 75 z = -5
