Question

Write the step you will use to separate the variable and then solve the equation (a) x+5=8.
mention the steps you will use to separate the variable and then solve the equation(b) 2(x-1)=10 (c) 5x-25=0​

Answer 1

Step-by-step explanation:

a.

x+5=8

x=8-5

x=3

b.

2(x-1)= 10

2x-2=10

2x=8

x=8/2

x=4

c.

5x-25=0

5x=25

x=25/5

x=5

Answer 2

Answer:

(a) 3=x

(b) x=6

(c) x=5

Step-by-step explanation:

(a) x+5-5=8-5

x+0 = 3

x = 3

(b) 2 (x-1)=10

x-1 =10÷2

x-1 =5

x =5+1

x =6

(c) 5x -25+25=0+25

5x-0 =25

5x =25

x =25÷5

x = 5
