Ineed with this math question. it is really hard. what is 2x+20=100

Step 1: Bring 20 to the right side of the equation by subtracting 20 to both sides (subtraction is the opposite of addition and will cancel 20 from the left side and bring it over to the right)

2x + (20 - 20) = 100 - 20

2x + 0 = 80

2x = 80

Step 2: To isolate x divide 2 to both sides (division is the opposite of multiplication and will cancel 2 from the left side and bring it over to the right)

2x ÷ 2 = 80 ÷ 2

x = 40

Check (plug in 40 for x and solve it like normal):

2(40) + 20 = 100

80 + 20 = 100

100 = 100 > Correct!

Hope this helped!
