Question

Please help me I am horrible at calculations

Solve for x when y=-0.27

5y+8(x−3y)=7x−12

Answer 1

X = -12.54 (I am a Math Class Topper in both 6th Grade an 7th Grade)

Explanation:

5 x .27 = 1.35

8x - (3 x .27) = .81

1.35 + 8x - .81 = 7x - 12

- 7x - 7x

----------------------------------

1.35 + X - .81 = -12

+ .81 +.81

---------------------------

1.35 + X = -11.19

-1.35 -1.35

-----------------------

X = -12.54
