Please help me I am horrible at calculations
Solve for x when y=-0.27

5y+8(x−3y)=7x−12

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

Step-by-step 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

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!
