x = 10

it means that x should equal 10. x + x = 20. x = 10

1.3 x 10-20

20 as 10 x 0 = 0 so is just 10 + 10 = 20

The solution is:- x = 0 and y = 5

x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.

Let the number is x So, X+20=69 X=69-20 X=49 THE NUMBER IS 49 SO, 49 plus 20 equal to 69 .•.

If x equals 10 and y equals 10, then 9x plus 8y equals 170.

4x =20x=20/4x=5

x equals 19

x=10

X= 5

(20 * x) + 3 = 5 20 * x = 2 x = 1/10

2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4

If you have an equation of x2 plus x2, it is the same as saying 2 times x plus 2 times x. This can be written as 2x + 2x or x2 + x2. It is the same, then, as 4x. For example, if x equals 5: 2(5) + 2(5) = 10 + 10 = 20. 20 also equals 4(5).

(1, 9)

Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10

5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10

3x+5=20 x=5 since 5x3+5=20

x = -9

2

(20 - x)/5

choose the negation of this statement. x plus y equals 10

x = 2

2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
