Question

Does anyone know how to solve these two math problems??!

Answer 1

1. 4.17

2. -2.2

Explanation:

Steps For Number 1

1. solve put 5x and 1 together, then put two and three together.

5 - 6x +5 = 4

2. 6x + 5 =

x= 0.83

5 - 0.83 = 4.17

Steps For Number 2

1. -3^3 = -9

2. -9 - 2(2y-2) = 5y +4

3. solve for y in 2y -2

y = 0

4. -9 - 2 = -7

5. -7 = 5y +4

5y +4 =-7 solve

-4 = -4

5y = -11 divide 5 by both

Answer 2

1. x = -1

2. y = -3

Explanation:

1. 5(5x+2) = 4(x+3)

5-5x+2 = 4x+12

5-5x+2 = 4x+12

-5x+3 = 4x+12

-3 -3

-5x = 4x+9

-4x -4x

-9x = 9

x = -1

2. -3³-2(2y-2) = 5y+4

-27-4y+4 = 5y+4

-4y-23 = 5y+4

-4 -4

-4y-27 = 5y

+4y +4y

-27 = 9y

y = -3
