Question

Solve the following equations)5y+10=4y-10b)4(x-3)=8

Answer 1

Step-by-step explanation:

a) 5y+10=4y-10

5y-4y= -10-10

y= -20

b) 4(x-3)=8

4x-12=8

4x=8+12

4x=20

x=20/4

x=5

Answer 2

Answer:

a)

5y + 10 = 4y - 10

⇒ 5y - 4y = -10 - 10

⇒ y = -20

y = (-20)

b)

4(x - 3) = 8

⇒ 4x - 12 = 8

⇒ 4x = 8 + 12

⇒ x = 20/4

⇒ x = 5

x = 5
