Question

Решите уравнения:а) -4(у-5)-3(у+4)=1б) -4(х+2)+15х-(х+3)=-1сначала раскройте скобки а потом решение

Answer 1

б)
 -4(х+2)+15х-(х+3)=-1
-4x-8+15x-x-3=-1
-4x+15x-x=-1+8+3
10x=10
x=1

Answer 2

А) -4y+20-3y-12=1
    -7y=1+12-20
    -7y=-7
    y=-7\-7
   y=1
Б)-4x-8+15x-x-3=-1
   10x=-1+8+3
   10x=10
   x=10\10
   x=1

Answer 3

Solving the Equations:

a) -4(у-5)-3(у+4)=1

First, let's simplify the equation by expanding the brackets and then solving for у:

-4(у-5)-3(у+4)=1 -4у + 20 - 3у - 12 = 1 -7у + 8 = 1 -7у = 1 - 8 -7у = -7 у = -7 / -7 у = 1 b) -4(х+2)+15х-(х+3)=-1

Similarly, let's simplify the equation by expanding the brackets and then solving for х:

-4(х+2)+15х-(х+3)=-1 -4х - 8 + 15х - х - 3 = -1 10х - 11 = -1 10х = -1 + 11 10х = 10 х = 10 / 10 х = 1 These are the solutions for the given equations.
