Question

. 1) (x + 58) - 37 = 91;3) 69 - (y - 28) = 13;​

Answer 1

Ответ:

1.

Объяснение:

(x+58)-37=91

x+58=91+37

x+58=128

x=128-58

x=70

Answer 2

It seems like you've provided two equations. Let's solve them step by step:

1. $x + 58 - 37 = 91$

First, combine the constants on the left side of the equation:

$x + 21 = 91$

Now, isolate $x$ by subtracting 21 from both sides:

$x = 91 - 21$

$x = 70$

So, the solution for the first equation is $x = 70$.

2. $69 - (y - 28) = 13$

Distribute the negative sign inside the parentheses:

$69 - y + 28 = 13$

Combine the constants on the left side:

$97 - y = 13$

Now, isolate $y$ by subtracting 97 from both sides:

$-y = 13 - 97$

$-y = -84$

Multiply both sides by -1 to solve for $y$:

$y = 84$

So, the solution for the second equation is $y = 84$.

Therefore, the solutions for the given equations are $x = 70$ and $y = 84$.
