Question

А) -2х+7х=-10 б)-3у+(4у-2)=0

Answer 1

A)5x=-10
x=-2
Б)-3y+4y-2=0
y=2

Answer 2

Let's solve each equation step by step:

А) -2х + 7х = -10

To solve this equation, combine the x terms on one side of the equation:

5х = -10

Next, isolate x by dividing both sides of the equation by 5:

x = -10 / 5

x = -2

So, the solution to the equation is x = -2.

б) -3у + (4у - 2) = 0

First, simplify the equation inside the parentheses:

-3у + 4у - 2 = 0

Combine the y terms:

(4у - 3у) - 2 = 0

у - 2 = 0

Next, isolate у by adding 2 to both sides of the equation:

у = 2

The solution to the equation is у = 2.
