Question

a) 3.Y+4 = 9
b) 5.X = 3+7
c) 6.Z - 4 = 20

Answer 1

Respuesta:

Explicación paso a paso:

a) 3.Y+4 = 9

3Y = 9 - 4

3Y = 5

Y = 5/3

b) 5.X = 3+7

5X = 10

X = 10/5

X = 2

c) 6.Z - 4 = 20

6Z = 20 + 4

6Z = 24

Z = 24/6

Z = 4

Answer 2

Respuesta:

a) y = 5/3; b) x = 2; c) z = 4

Explicación paso a paso:

a) 3y + 4 = 9

3y + 4 - 4 = 9 - 4

3y = 5

y =

$\frac{5}{3}$

b) 5x = 3 + 7

5x = 10

x = 2

c) 6z - 4 = 20

6z = 24

z = 4
