7x-2(x-10)=40

7 x - 2 (x - 10) = 40

x = 4

Solution steps

7 x - 2 (x - 10) = 40

Expand

- 2 (x - 10) : - 2 x + 20

7 x - 2 x + 20 = 40

Add similar elements:

7 x - 2 x = 5 x

5 x + 20 = 40

Move

20

to the right side

5 x = 20

Divide both sides by

5

x = 4

a x + 3 x + a y + 3 y

\frac{( 16 x - 1 )}{4} + 44 \geq x - \frac{( 20 x + 2 )}{6}

3 x = 75
