(4x-2)-(3x+1)=8

解答

(4 x - 2) - (3 x + 1) = 8

解答

x = 11

求解步骤

(4 x - 2) - (3 x + 1) = 8

4 x - 2 - (3 x + 1) = 8

2 y = - 30

solvefor f,(f+g)(4)=6

so l v e f or f, (f + g) (4) = 6

solvefor x,2x=5-3y

so l v e f or x, 2 x = 5 - 3 y

-5(4x-4)-2x-4=-28-28

- 5 (4 x - 4) - 2 x - 4 = - 28 - 28

solvefor x,12y-2x=12

so l v e f or x, 12 y - 2 x = 12
