Question

(85+х)•3-72=219. (171+(36-y):3=58

Answer 1

Пошаговое объяснение:

(85+x)×3-72=219

255+3x-72=219

183+3x=219

3x=219-183

3x=36

x=36:3

x= 12

(171+(36-y)):3=58

(171+36-y):3=58

(207-y):3=58

207-y:3=58

207-y=174

-y=174-207

-y=-33

y=33

Answer 2

Let's solve the equations step by step:

Equation 1: (85 + x) * 3 - 72 = 219

First, distribute the multiplication:

255 + 3x - 72 = 219

Combine like terms:

3x + 183 = 219

Now, isolate the variable:

3x = 219 - 183

3x = 36

Divide both sides by 3:

x = 36 / 3

x = 12

So the solution for Equation 1 is x = 12.

Equation 2: (171 + (36 - y)) / 3 = 58

First, simplify the expression inside the parentheses:

(171 + 36 - y) / 3 = 58

Combine like terms:

207 - y / 3 = 58

Next, isolate the variable:

-y / 3 = 58 - 207

-y / 3 = -149

Multiply both sides by 3:

-y = -149 * 3

-y = -447

Multiply both sides by -1 to isolate y:

y = 447

So the solution for Equation 2 is y = 447.

Therefore, the solutions to the given equations are x = 12 and y = 447.
