Solve the equation (-10x + 1 + 7x = 37)

x = - 12

Step-by-step explanation:

- 10x + 1 + 7x = 37

- 3x + 1 = 37

- 3x + 1 - 1 = 37 - 1

- 3x = 36

- 3x ÷ - 3 = 36 ÷ - 3

x = - 12

x = -12

Step-by-step explanation: first you combine like terms/simplify the equation: -10x + 1 + 7x = 37 turns into -3x + 1 = 37.

then subtract 1 from both sides: -3x + 1 = 37 then -3x + 1 - 1 = 37 - 1 then -3x = 37 - 1 then -3x = 36.

then divide both sides of the equation by -3 and then you're done

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
